High [CVE-2026-79986] Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Azure Files component
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Azure Files component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel remote-file consumers poll a directory on a remote server and build the absolute remote path of each file by concatenating the configured directory with the file name reported in the server's directory listing. That concatenation (FtpUtils.absoluteFilePath and GenericFileConsumer) applied no lexical normalization and no check that the result stayed inside the directory being polled, and the resulting path became the operand for every subsequent remote operation on the file: retrieval (FtpOperations.retrieveFile / SftpOperations, reached from GenericFileConsumer where the retrieve name is taken verbatim from GenericFile.getAbsoluteFilePath), deletion when delete=true (GenericFileDeleteProcessStrategy), and renaming when move, preMove, moveFailed or readLock=rename is configured (GenericFileProcessStrategySupport and GenericFileRenameExclusiveReadLockStrategy). Neither isValidFile nor isMatched performed any containment check. A listing entry that is not a single path segment therefore resolved to a path outside the configured polling directory, causing Camel to read, delete or rename files outside it using the endpoint's own credentials.
High [CVE-2026-79985] Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel SMB component
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel SMB component. This issue affects Apache Camel: from 4.2.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel remote-file consumers poll a directory on a remote server and build the absolute remote path of each file by concatenating the configured directory with the file name reported in the server's directory listing. That concatenation (FtpUtils.absoluteFilePath and GenericFileConsumer) applied no lexical normalization and no check that the result stayed inside the directory being polled, and the resulting path became the operand for every subsequent remote operation on the file: retrieval (FtpOperations.retrieveFile / SftpOperations, reached from GenericFileConsumer where the retrieve name is taken verbatim from GenericFile.getAbsoluteFilePath), deletion when delete=true (GenericFileDeleteProcessStrategy), and renaming when move, preMove, moveFailed or readLock=rename is configured (GenericFileProcessStrategySupport and GenericFileRenameExclusiveReadLockStrategy). Neither isValidFile nor isMatched performed any containment check. A listing entry that is not a single path segment therefore resolved to a path outside the configured polling directory, causing Camel to read, delete or rename files outside it using the endpoint's own credentials.
High [CVE-2026-79984] Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Mina SFTP component
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel Mina SFTP component. This issue affects Apache Camel: from 4.18.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel remote-file consumers poll a directory on a remote server and build the absolute remote path of each file by concatenating the configured directory with the file name reported in the server's directory listing. That concatenation (FtpUtils.absoluteFilePath and GenericFileConsumer) applied no lexical normalization and no check that the result stayed inside the directory being polled, and the resulting path became the operand for every subsequent remote operation on the file: retrieval (FtpOperations.retrieveFile / SftpOperations, reached from GenericFileConsumer where the retrieve name is taken verbatim from GenericFile.getAbsoluteFilePath), deletion when delete=true (GenericFileDeleteProcessStrategy), and renaming when move, preMove, moveFailed or readLock=rename is configured (GenericFileProcessStrategySupport and GenericFileRenameExclusiveReadLockStrategy). Neither isValidFile nor isMatched performed any containment check. A listing entry that is not a single path segment therefore resolved to a path outside the configured polling directory, causing Camel to read, delete or rename files outside it using the endpoint's own credentials.
High [CVE-2026-79983] Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel FTP component
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel FTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel remote-file consumers poll a directory on a remote server and build the absolute remote path of each file by concatenating the configured directory with the file name reported in the server's directory listing. That concatenation (FtpUtils.absoluteFilePath and GenericFileConsumer) applied no lexical normalization and no check that the result stayed inside the directory being polled, and the resulting path became the operand for every subsequent remote operation on the file: retrieval (FtpOperations.retrieveFile / SftpOperations, reached from GenericFileConsumer where the retrieve name is taken verbatim from GenericFile.getAbsoluteFilePath), deletion when delete=true (GenericFileDeleteProcessStrategy), and renaming when move, preMove, moveFailed or readLock=rename is configured (GenericFileProcessStrategySupport and GenericFileRenameExclusiveReadLockStrategy). Neither isValidFile nor isMatched performed any containment check. A listing entry that is not a single path segment therefore resolved to a path outside the configured polling directory, causing Camel to read, delete or rename files outside it using the endpoint's own credentials.
High [CVE-2026-78165] Deserialization of Untrusted Data vulnerability in Apache Camel Spring Redis component
Deserialization of Untrusted Data vulnerability in Apache Camel Spring Redis component. This issue affects Apache Camel: from 2.11.0 before 4.18.5, from 4.19.0 before 4.22.1. RedisConfiguration.getSerializer lazily built a bare JdkSerializationRedisSerializer whenever no serializer option was configured, and that instance was used for every read the component performs. Spring's implementation delegates through DeserializingConverter to DefaultDeserializer, which reads the bytes with a ConfigurableObjectInputStream and installs no java.io.ObjectInputFilter on the stream, so an arbitrary serialized class graph was materialised and its readObject method executed. RedisConsumer.setBody applied that serializer to the raw bytes of every message published to the subscribed channels, before the Exchange was constructed and therefore before any route logic could inspect the message, so an actor able to issue PUBLISH on a subscribed channel reached the deserialization sink directly. The same default serializer backed the RedisTemplate built by RedisConfiguration.createDefaultTemplate, so the producer read commands GET, HGET, HGETALL and HVALS deserialized whatever was stored in the Redis keyspace, and SpringRedisIdempotentRepository shared that template.
High [CVE-2026-78164] Improper Neutralization of Special Elements Used in a Template Engine and Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel HTTP, Netty HTTP, Undertow and Vert.x HTTP components
Improper Neutralization of Special Elements Used in a Template Engine and Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel HTTP, Netty HTTP, Undertow and Vert.x HTTP components. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Camel HTTP producer families let an inbound message override the endpoint URI through the CamelHttpUri and CamelRestHttpUri headers, and then passed that message-supplied string through CamelContext.resolvePropertyPlaceholders() before using it. Property-placeholder resolution is a configuration-resolution facility, not a URI-parsing step: it reaches operating-system environment variables, JVM system properties, every PropertiesFunction registered on the classpath - including the secret functions - and, through camel-bean, the invocation of a no-argument method on any bean in the registry. Applying it to Exchange content therefore turned a URI string into a configuration- and bean-evaluation context. A route author opted into none of this: a plain static to(" ) was sufficient.
Medium [CVE-2026-91858] FopProducer transforms the incoming XSL-FO message body by creating a javax.xml.transform.TransformerFactory through TransformerFactory.newInstance and enabling only FEATURE_SECURE_PROCESSING before running an identity transform over the body
FopProducer transforms the incoming XSL-FO message body by creating a javax.xml.transform. TransformerFactory through TransformerFactory.newInstance() and enabling only FEATURE_SECURE_PROCESSING before running an identity transform over the body. On the JDK's built-in transformer, that feature alone already empties the accessExternalDTD and accessExternalStylesheet limits, so an external DTD or entity is refused. When a third-party JAXP TransformerFactory such as Saxon-HE is on the classpath, for example because the application also uses camel-xslt-saxon or camel-saxon, TransformerFactory.newInstance() returns that implementation instead, and FEATURE_SECURE_PROCESSING on its own does not restrict external resource access on it. A DOCTYPE with an external subset, or an external general entity, declared in the XSL-FO document is then resolved and expanded while the body is transformed. An external sender whose XSL-FO reaches a fop producer could therefore read files readable by the Camel process and cause the process to issue requests to hosts the document names. camel-fop does not bring such a factory itself, and excludes Xalan, so a default deployment using the JDK transformer is not affected; the issue is reachable only where another component has placed an alternative JAXP TransformerFactory on the classpath. Affected product named by the advisory: Apache Camel.
Medium [CVE-2026-85317] Use of Cache Containing Sensitive Information vulnerability in Apache Camel HTTP component
Use of Cache Containing Sensitive Information vulnerability in Apache Camel HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The OAuth2 client token cache is global to the JVM, and its key omitted several of the fields that determine what a token actually authorises: the requested scope, the resource indicator, and the token endpoint the token was obtained from. Two endpoints differing only in those fields therefore shared a cache entry, and an endpoint could be served a token minted for a different scope, a different resource, or by a different authorization server. The consequence is a request carrying broader authority than the endpoint was configured for, or a token presented to a party it was not issued for. Reaching it requires a deployment that configures more than one OAuth2 endpoint differing in exactly those fields, which is why the severity is assessed low. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The cache key now includes every field that shapes the token, so entries are no longer shared between endpoints that differ in any of them. For deployments that cannot upgrade immediately, run endpoints that differ in scope, resource indicator or token endpoint in separate JVMs so that they do not share the cache.
Medium [CVE-2026-85316] Insufficient Granularity of Access Control vulnerability in Apache Camel Platform HTTP component
Insufficient Granularity of Access Control vulnerability in Apache Camel Platform HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The component decided whether an endpoint ran in proxy mode by testing whether its configured path started with the string proxy, rather than by matching the path exactly. Any endpoint whose path merely begins with those characters - proxyStatus, proxy-config, proxying and so on - therefore became a proxy endpoint without the route author asking for it. A proxy endpoint forwards requests onward, so an endpoint that was intended to serve its own content instead relays traffic on behalf of whoever calls it, which is both a request forgery primitive and an exposure of whatever the forwarding path can reach. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Proxy mode is now selected by an exact path match rather than by prefix. For deployments that cannot upgrade immediately, rename any endpoint path that begins with proxy but is not intended to be a proxy.
Medium [CVE-2026-85315] Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel gRPC component
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel gRPC component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When a route behind a gRPC consumer failed, the exception's message was placed into the gRPC status description. Unlike the status cause, which stays local to the server, the description is transmitted to the calling client, so an external caller able to provoke a failure could read the internal error message. What that discloses depends on the exception, and in practice includes class and package names, paths, host names and connection detail carried in messages. This is the gRPC member of the same unmuted-consumer-exception family as the knative, mina and CXF advisories published alongside it. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. A muteException consumer option, defaulting to true, puts a generic description in the status instead of the route exception's message. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, map failures onto an explicit status in an onException handler so the framework never copies the exception message into the description.
Medium [CVE-2026-46584 +1] Improper Input Validation vulnerability in Apache Camel Mail component
Improper Input Validation vulnerability in Apache Camel Mail component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. CVE-2026-46584 addressed mail headers reaching the Exchange without passing through a header filter, but the MimeMultipart data format retained an unfiltered path: unmarshalling a multipart message mapped mail.smtp headers onto the Exchange with no filter applied. Those names sit outside the Camel namespace that consumer filters block, so a message crafted by an external sender could still set them, and the mail.smtp namespace influences how a downstream mail producer connects and sends. This is an incomplete fix of CVE-2026-46584 rather than a new class of defect: a deployment that applied that advisory and considered camel-mail settled remained exposed on this path. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The MimeMultipart data format now applies the header filter on unmarshal, closing the path CVE-2026-46584 left open. For deployments that cannot upgrade immediately, strip the namespace after the data format with removeHeaders("mail.smtp*") before any mail producer.
Medium [CVE-2026-85313] Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Jetty component
Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Jetty component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. Setting enableCORS on a Jetty endpoint installed Jetty's CrossOriginFilter with its stock defaults, which accept every origin and allow credentials. An operator asking for CORS therefore obtained a policy that lets a page on any origin make credentialed cross-origin requests to the endpoint and read the responses, without any indication that turning the option on had chosen an allow-all policy rather than an empty one to be filled in. This is the same defect class as the platform-http-vertx advisory published alongside it, in a different component. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. A deployment that relied on any origin being accepted must now list its origins explicitly. For deployments that cannot upgrade immediately, configure the CrossOriginFilter parameters explicitly rather than relying on what enableCORS installs, naming the allowed origins.
Medium [CVE-2026-85312] Improper Input Validation vulnerability in Apache Camel Core component
Improper Input Validation vulnerability in Apache Camel Core component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The saga processor consulted a header named Long-Running-Action to decide which saga an exchange belonged to. The name carries no Camel prefix, so it sits outside the namespace that consumer header filters block, and an external sender could supply it on an inbound message. That let the sender name the saga the exchange joined, attaching their request to a long-running action started by someone else, or causing compensation to be associated with an action they did not initiate. The header is only consulted by a saga service that uses it, which bounds the exposure to deployments running sagas over an LRA coordinator. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The header is now consulted only for a saga service that actually uses it, rather than on every exchange. For deployments that cannot upgrade immediately, strip the header at the trust boundary with removeHeaders("Long-Running-Action") on every consumer that accepts messages from an untrusted sender.
Medium [CVE-2026-85300] Incorrect Default Permissions vulnerability in Apache Camel PQC component
Incorrect Default Permissions vulnerability in Apache Camel PQC component. This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1. When the component wrote generated key material to disk it did so with the permissions the process default umask produced, rather than restricting the file to its owner. On a host whose umask allows group or world read, the private key was therefore readable by other local accounts. The exposure is to a local party rather than to the remote sender that the Camel threat model treats as the primary adversary, which is why the severity is assessed low, but the consequence where it applies is complete: possession of the private key defeats every signature and key exchange the deployment performs with it. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Key material is now written with owner-only permissions. For deployments that cannot upgrade immediately, place the key directory on a path only the service account can traverse, and tighten the process umask. Key material already written with permissive permissions should be treated as exposed and rotated.
Medium [CVE-2026-85301] Improper Authentication vulnerability in Apache Camel Keycloak component
Improper Authentication vulnerability in Apache Camel Keycloak component. This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.1. The security processor validated the issuer of an introspected token only when the introspection response actually carried an iss claim. When the claim was absent the check was skipped rather than treated as a failure, so a token that the configured issuer did not mint could be accepted provided the introspection endpoint answered without naming an issuer. Reaching this requires an introspection endpoint that omits iss and accepts tokens from more than one issuer, which is not the default Keycloak arrangement, hence the low severity; where that arrangement exists the consequence is that the deployment authenticates a caller it should have rejected. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. An absent iss claim is now treated as a validation failure rather than as a reason to skip the check. For deployments that cannot upgrade immediately, ensure the introspection endpoint returns the iss claim, and that it serves exactly one issuer.
Medium [CVE-2026-85296] Exposure of Data Element to Wrong Session vulnerability in Apache Camel AS2 component
Exposure of Data Element to Wrong Session vulnerability in Apache Camel AS2 component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. Signing material belonging to an individual request was stored in state that is shared across requests rather than confined to the request being processed. Where a deployment serves more than one trading partner, concurrent or successive requests could therefore observe each other's material, and a Message Disposition Notification could be signed with the key of a partner other than the one the receipt was for. The result is cross-partner key confusion: a receipt attributable to the wrong partner, and one partner's signing material used while handling another partner's exchange. AS2 deployments are typically multi-partner by design, so the condition is reached by ordinary concurrent traffic rather than by anything the attacker must arrange. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Per-request signing keys are now confined to the request being processed in ResponseMDN. For deployments that cannot upgrade immediately, run a separate Camel context per trading partner so that no signing material is shared between them.
Medium [CVE-2026-85260] Insertion of Sensitive Information into Log File vulnerability in Apache Camel MLLP component
Insertion of Sensitive Information into Log File vulnerability in Apache Camel MLLP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The camel-mllp component carries a logPhi option that governs whether HL7 payload content may be written to the log. It defaulted to true, so a deployment that did nothing logged protected health information out of the box. Two further paths wrote payload content to the log regardless of the setting, so even an operator who had turned logPhi off was still exposed on those paths. MLLP is used to carry HL7 clinical messages, so the content concerned is patient data, and it reached ordinary application logs where it is subject to whatever retention, aggregation and access the deployment applies to logs generally rather than to clinical records. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. This is a changed default: a deployment that relied on payload logging must now set logPhi=true explicitly. Because the upgrade guide for a change like this lives on the main branch only, operators upgrading within the 4.18.x or 4.22.x lines should treat this advisory as the notice of that change.
Medium [CVE-2026-85257] Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel CXF component
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel CXF component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When a route behind a CXF SOAP consumer failed with an exception the service contract does not declare, the exception was described back to the SOAP client in the fault: CXF copies the message into the SOAP faultstring, and can be configured to place the stack trace in the fault detail. An external caller able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever the exception message carries. Declared faults, annotated @WebFault, are a different matter: those are part of the published contract that clients are written against, and suppressing them would break the service rather than protect anything. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. A muteException consumer option, defaulting to true, replaces an undeclared route failure with a generic fault carrying no class name, message or stack trace. Faults the contract declares are reported exactly as before. Set muteException=false to restore the previous output.
Medium [CVE-2026-85254] Improper Handling of Case Sensitivity vulnerability in Apache Camel Platform HTTP component
Improper Handling of Case Sensitivity vulnerability in Apache Camel Platform HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The guard that prevents a request header being reflected into the response compared header names case sensitively, while HTTP header names are case insensitive. A caller could therefore defeat the suppression simply by varying the case of the header name. HTTP/2 makes the problem unconditional rather than optional: the protocol requires header names to be lowercase on the wire, so the comparison never matched and the suppression was inert for every request on an HTTP/2 connection. The consequence is that content the caller chose is echoed back in the response, which is the basis for response-splitting and cache-poisoning style attacks against whatever sits in front of the Camel endpoint. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Request header names are now compared case insensitively, so the suppression holds regardless of casing and works under HTTP/2. For deployments that cannot upgrade immediately, strip the headers in question in front of the Camel endpoint, or remove them from the response in the route rather than relying on the built-in suppression.
Medium [CVE-2026-85249] Improper Input Validation vulnerability in Apache Camel Tika component
Improper Input Validation vulnerability in Apache Camel Tika component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Tika producer mapped every metadata key parsed out of the submitted document onto the Exchange as a header, with no filter applied. Document metadata is attacker-controlled content: the party that supplies the file chooses the metadata keys it carries. A crafted document could therefore set Exchange headers that the rest of the route depends on, including headers in the Camel namespace such as CamelFileName, which downstream components use to decide where content is written. The pattern is the same header-injection class as the consumer advisories published previously, reached here through parsed file content rather than through a protocol header. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Parsed document metadata is now filtered through a HeaderFilterStrategy before it is mapped onto the Exchange. A route that was reading a metadata-derived header the filter now blocks will see it missing. For deployments that cannot upgrade immediately, strip the Camel namespace after the Tika producer with removeHeaders("Camel*") before any component that acts on those headers.
Medium [CVE-2026-85248] Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Apache Camel PQC component
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Apache Camel PQC component. This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1. The producer held a single java.security. Signature instance and used it for every exchange without synchronizing access. Signature is stateful and is not thread safe: update() accumulates the data to be signed or verified, and verify() consumes that accumulated state. With concurrent exchanges sharing one instance the update and verify calls of different messages interleave, so a verification can complete against data that belongs to another exchange, or against a partially accumulated buffer. The outcome is non-deterministic and includes a verification reporting success for a message whose signature was never actually checked, which defeats the guarantee the component exists to provide. Reaching it requires concurrent traffic through the same endpoint, which is the ordinary condition for a Camel route under load. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The Signature instance is no longer shared across concurrent exchanges.
Medium [CVE-2026-85247] Improper Certificate Validation vulnerability in Apache Camel Knative component
Improper Certificate Validation vulnerability in Apache Camel Knative component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When SSL was enabled on the Knative HTTP client but no truststore was configured, the client options fell back to trusting every presented certificate rather than to the JVM's default trust anchors. A deployment that switched TLS on without also configuring a truststore therefore obtained an encrypted connection with no peer authentication, which an attacker positioned on the network path can terminate and read. The dangerous state is reached by omission rather than by an explicit opt-in, which is what makes it a framework defect: turning TLS on should not be the thing that turns certificate validation off. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. With no truststore configured the trust options are now left unset so the JVM default trust anchors apply, the same fallback SSLContextParameters and the rest of Camel use. Trusting every certificate is now reached only by asking for it explicitly through the trust.all property, which remains available for development against a cluster with a self-signed certificate. For deployments that cannot upgrade immediately, configure a truststore explicitly wherever SSL is enabled.
Medium [CVE-2026-85246] Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Mina component
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Mina component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When processing of an exchange failed, the Mina consumer wrote exchange.getException() straight back over the socket to the remote peer. Over a textline codec that hands the peer the exception's class name and message; over the object codec it hands over the serialised exception, cause chain included. A remote peer able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever a message or nested cause happens to carry, which in practice can include paths, host names and connection detail. The consumer had no option to suppress this, unlike the HTTP-family consumers aligned by CAMEL-23651. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. A muteException consumer option, defaulting to true, replaces the route exception with a generic one carrying no class name, message or stack trace, while still writing a reply so that a synchronous peer is not left to time out. Set muteException=false to restore the previous behaviour.
Medium [CVE-2026-85245] Exposure of Data Element to Wrong Session vulnerability in Apache Camel Thrift component
Exposure of Data Element to Wrong Session vulnerability in Apache Camel Thrift component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Thrift data format unmarshalled incoming data into the shared defaultInstance of the target type rather than into a fresh copy, and returned that shared object as the exchange body. Because the instance is shared process-wide, state written while unmarshalling one message stayed on the object and was visible to every later message that used the same type. Fields absent from a later payload retained the previous message's values, so content belonging to one sender could be read while processing another sender's message, and concurrent exchanges could observe each other's partially written state. In a deployment that serves more than one tenant or user through the same route, that is disclosure of one party's data to another. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Unmarshalling now deserializes into a copy, so each exchange gets its own instance and no state carries between messages. For deployments that cannot upgrade immediately, copy the unmarshalled body into a new instance immediately after the data format runs, and do not retain references to the returned object.
Medium [CVE-2026-85243] Improper Validation of Integrity Check Value vulnerability in Apache Camel Crypto PGP component
Improper Validation of Integrity Check Value vulnerability in Apache Camel Crypto PGP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. unmarshal() verified the modification detection code only when the message was an OpenPGP symmetrically encrypted integrity protected data packet. The older symmetrically encrypted data packet carries no such code, and OpenPGP's CFB mode is malleable without one, so a message using that packet skipped the check altogether. The packet type is chosen by whoever produced the message, which left the sender - or anyone able to rewrite the message in transit - deciding whether the integrity check applied at all. The existing integrity option governs marshalling only and had no decrypt-side counterpart, so a deployment could not require integrity protection on the messages it accepted. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. A requireIntegrityProtection option, defaulting to true, now rejects a message that is not integrity protected. Note that signatureVerificationOption still defaults to optional, so a message carrying no signature is accepted; the two options together are what give a decrypted message authenticity and not only confidentiality.
Medium [CVE-2026-84181] Improper Authentication vulnerability in Apache Camel Shiro component
Improper Authentication vulnerability in Apache Camel Shiro component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Shiro security processor skipped credential verification when the subject already bound to the current thread carried the same principal as the incoming exchange. Because the thread that carries a Camel exchange is drawn from a pool and reused across exchanges, a subject left bound by an earlier authenticated exchange could satisfy the check for a later one that presented no valid credentials of its own. The password on the incoming exchange was, in that case, never verified. The condition depends on thread reuse and on the principal matching, which is why it is not reached on every request, but it requires nothing of the attacker beyond sending a request naming a principal that is in active use. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The processor now verifies the presented credentials on every exchange rather than accepting a subject already bound to the thread. Setting alwaysReauthenticate=false restores the previous behaviour for deployments that depend on it.
Medium [CVE-2026-84180] Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Knative component
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Knative component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When processing of an exchange failed on the consumer side, the Knative HTTP consumer wrote the resulting exception back to the remote caller as the response body, including its class name, message and stack trace. An external sender could therefore provoke a failure and read internal detail about the deployment: class and package names, file system or host names carried in exception messages, and the shape of the route. That detail is useful for building a more targeted attack, and where an exception message embeds configuration or connection strings it is disclosure in its own right. camel-knative was the remaining HTTP-family consumer that had not been aligned with the muteException behaviour established for the other HTTP consumers by CAMEL-23651. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The consumer now honours a muteException option that defaults to true, so a route failure returns an empty body with the error status rather than the exception. Set muteException=false to restore the previous output.
Medium [CVE-2026-84178] Cross-Site Request Forgery (CSRF) vulnerability in Apache Camel OAuth component
Cross-Site Request Forgery (CSRF) vulnerability in Apache Camel OAuth component. This issue affects Apache Camel: from 4.11.0 before 4.18.5, from 4.19.0 before 4.22.1. The authorization code callback did not carry a state parameter binding it to the authorization request that started the flow, and the callback did not verify one. An authorization code obtained in any browser could therefore be redeemed at the callback and associated with whichever session presented it, which is login cross-site request forgery: a victim can be silently signed in as an identity the attacker controls, so that actions the victim then performs, and data they then submit, land in the attacker's account. The same unvalidated callback handling also allowed the post-authentication redirect target to be influenced, giving an open redirect from a trusted origin. The state check runs before the authorization code is redeemed, so these paths are reachable without any interaction with the identity provider. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The authorization request now issues a state value bound to the session, and the callback rejects a request whose state is absent or does not match, stopping the route with a 400 response.
Medium [CVE-2026-84176] Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Platform HTTP Vertx component
Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Platform HTTP Vertx component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. createCorsHandler() set Access-Control-Allow-Credentials: true outside the origin check, so the header went out on every response to a request carrying an Origin header, including responses to origins the handler had just decided not to allow. When camel.server.cors.origins is unset, the handler treats every origin as allowed and echoes the caller's own Origin back as Access-Control-Allow-Origin. Together those produce the credentialed any-origin configuration that the fetch specification refuses to express as a literal wildcard, which is precisely why reflecting the origin is the usual way around that rule. A page on any origin could therefore make credentialed cross-origin requests to the Camel endpoint and read the responses. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Access-Control-Allow-Credentials is now sent only when the request origin matched an origin the operator actually configured.
Medium [CVE-2026-78163] Server-Side Request Forgery (SSRF), Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') and Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel Docling component
Server-Side Request Forgery (SSRF), Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') and Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel Docling component. This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.1. DoclingProducer decided what a String message body meant by inspecting its prefix. A body starting with http:// or https:// was handed to Docling as a remote URL to fetch, a body starting with / or containing a backslash was read from the local filesystem, and anything else was written to a temporary file and converted as document content. The mode was chosen implicitly and no endpoint option allowed a route author to pin the component to a single interpretation, so a route that means convert whatever text arrives in the body silently became a fetcher of remote resources or a reader of local files whenever the text happened to begin with one of those prefixes. The only guard applied to the derived value was a size check, and that check was wrapped in an existence test, so a path that resolved to nothing, or to a pseudo-file reporting a size of zero, passed without being checked at all.
High [CVE-2026-103413] Improper input validation vulnerability in Apache Camel Karavan
Improper input validation vulnerability in Apache Camel Karavan. When a deployment was started, Karavan unmarshalled a project's `kubernetes.yaml` and applied every resource it contained to the cluster without restricting the resource kinds, without rejecting security-sensitive pod options, and without pinning the target namespace. An authenticated user of any role could therefore have Karavan apply arbitrary Kubernetes resources within the reach of its service account, including pods requesting hostNetwork, hostPID, hostIPC, hostPath volumes, host ports, privileged containers, privilege escalation or added capabilities. This issue affects Apache Camel Karavan: from 4.0.0 before 4.22.1. Users are recommended to upgrade to version 4.22.1, which fixes the issue.
High [CVE-2026-103412] Improper limitation of a pathname to a restricted directory ('path traversal') vulnerability in Apache Camel Karavan
Improper limitation of a pathname to a restricted directory ('path traversal') vulnerability in Apache Camel Karavan. A project file name supplied through the project file API was used verbatim as a path segment when the project was written to the working copy for a Git commit, so a name containing `../` sequences caused the file content to be written outside the project directory, to any location writable by the Karavan process. An authenticated user of any role could use this to overwrite application configuration or files on the application classpath and so execute code in the Karavan container. This issue affects Apache Camel Karavan: from 3.18.0 before 4.22.1. Users are recommended to upgrade to version 4.22.1, which fixes the issue.
High [CVE-2026-88789] Improper Restriction of XML External Entity Reference in the XSLT support extension (camel-quarkus-support-xalan) in Apache Camel Quarkus from 3.2.0 before 3.33.3 and from 3.34.0 before 3.40.0 on all platforms allows an attacker who supplies the XML document being transformed to read local files or issue requests to internal network locations via an external entity declaration in that document
Improper Restriction of XML External Entity Reference in the XSLT support extension (camel-quarkus-support-xalan) in Apache Camel Quarkus from 3.2.0 before 3.33.3 and from 3.34.0 before 3.40.0 on all platforms allows an attacker who supplies the XML document being transformed to read local files or issue requests to internal network locations via an external entity declaration in that document. The extension supplies its own Xalan-backed TransformerFactory to the xslt component and registers it as the JAXP default. Xalan-J 2.7.x predates JAXP 1.5 and does not honour javax.xml.XMLConstants.ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET, so the external access restrictions Apache Camel applies to the TransformerFactory it creates were not in effect. On the xslt component path this affects message bodies that reach the transformer already as a javax.xml.transform. Source; bodies of other types are converted to a SAXSource by Apache Camel with external entities and external DTD loading disabled, and are not affected. Because the factory is also the JAXP default, other code in the application obtaining one through TransformerFactory.newInstance() loses the same restrictions without error.
High [CVE-2026-86792] Apache Airflow Apache Kafka provider versions 1.15.0 before 2.0.0 resolve dotted-path strings found in a Kafka connection's `extra` field into Python callables via `import_string`, with no allowlist, and hand them to the confluent-kafka client which invokes them
Apache Airflow Apache Kafka provider versions 1.15.0 before 2.0.0 resolve dotted-path strings found in a Kafka connection's `extra` field into Python callables via `import_string`, with no allowlist, and hand them to the confluent-kafka client which invokes them. Deployments that have enabled the Kafka event producer — `dag_run_events_enabled` or `task_instance_events_enabled`, both disabled by default — build that client inside the scheduler process, so a user whose only privilege is editing Airflow connections gains arbitrary code execution in the control plane; the Airflow security model limits connection-configuration users to code execution on workers, not the scheduler. Deployments using Google Managed Kafka are not affected, because that code path overwrites any user-supplied `oauth_cb`; plain brokers and Amazon MSK are exposed. Users are recommended to upgrade to apache-airflow-providers-apache-kafka 2.0.0 or later, which adds an allowlist configuration option for connection-string callbacks.
Critical [CVE-2026-80351] Improper neutralization of directives in dynamically evaluated code ('eval injection') vulnerability in Apache Camel K
Improper neutralization of directives in dynamically evaluated code ('eval injection') vulnerability in Apache Camel K. An improper neutralization of directives in dynamically evaluated Maven configuration allows tenant-controlled repository content to influence code execution within the operator pod, potentially enabling tenants to execute arbitrary code with the privileges of the operator. This issue affects Apache Camel K: from 2.0.0 before 2.9.3, from 2.10.1 before 2.10.2. Users are recommended to upgrade to version 2.9.3, 2.10.2 or 2.11.0, which fixes the issue.
Critical [CVE-2026-80352] Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Camel K
Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Camel K. A YAML injection vulnerability in custom resource configuration allows an authorized CR author to inject arbitrary Kubernetes objects, potentially enabling unauthorized resource creation with the privileges of the operator. This issue affects Apache Camel K: from 2.0.0 before 2.9.3, from 2.10.1 before 2.10.2. Users are recommended to upgrade to version 2.9.3, 2.10.2 or 2.11.0, which fixes the issue.
Critical [CVE-2026-49364] Apache Artemis: unauthenticated network-adjacent attacker can leverage discovery to capture cluster administrative credentials during the initial cluster connection handshake
An unauthenticated network-adjacent attacker can leverage discovery to capture cluster administrative credentials during the initial cluster connection handshake. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
Critical [CVE-2026-57967] Apache Artemis, Apache ActiveMQ Artemis: Missing authentication on CORE protocol session reattachment
An unauthenticated remote attacker can craft a CORE protocol SESSION_REATTACH packet to steal an existing session and assume ongoing execution of the previously authenticated session. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
Critical [CVE-2026-67593] Apache Artemis: remote attacker can craft an Openwire RemoveSubscriptionInfo command to cause the deletion of a queue on the Artemis broker before the connection authentication and authorization stage or at any time thereafter
A remote attacker can craft an Openwire RemoveSubscriptionInfo command to cause the deletion of a queue on the Artemis broker before the connection authentication and authorization stage or at any time thereafter. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
High [CVE-2026-80354] Authorization bypass through User-Controlled key vulnerability in Apache Camel K
Authorization bypass through User-Controlled key vulnerability in Apache Camel K. An authorization vulnerability in custom resource resolution allows a tenant to reference secrets by name in the operator namespace, potentially exposing secrets belonging to other tenants or operator components. This issue affects Apache Camel K: from 2.0.0 before 2.9.3, from 2.10.1 before 2.10.2. Users are recommended to upgrade to version 2.9.3, 2.10.2 or 2.11.0, which fixes the issue.
High [CVE-2026-49362] Apache Artemis: unauthenticated remote attacker can create arbitrary durable queues via the CORE protocol, leading to unauthorized broker state manipulation and potential denial of service
An unauthenticated remote attacker can create arbitrary durable queues via the CORE protocol, leading to unauthorized broker state manipulation and potential denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.

An unauthenticated remote attacker connecting with the CORE protocol can discover cluster node details by sending a SUBSCRIBE_TOPOLOGY request prior to authentication. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
Medium [CVE-2026-57822] Apache Artemis: When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise
When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise. The permitted types allow to craft a payload causing excessive computation and pinning the processing thread, leading to denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.3.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
Medium [CVE-2026-75880] Apache Artemis, Apache ActiveMQ Artemis: Message selector wildcard handling could lead to denial of service
An authenticated client could attach a consumer with a selector containing crafted wildcard usage that results in excessive evaluation during message delivery attempts, occupying a shared broker thread and leading to denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes this issue.
High [CVE-2026-74761] Improper input validation in TopicRegion in Apache ActiveMQ, Apache ActiveMQ Broker, and Apache ActiveMQ All on all platforms
Improper input validation in TopicRegion in Apache ActiveMQ, Apache ActiveMQ Broker, and Apache ActiveMQ All on all platforms. An authenticated client can spoof clientId when removing a durable topic subscription. This issue affects Apache ActiveMQ Broker: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ All: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ: before 5.19.11, from 6.0.0 before 6.3.2. Users are recommended to upgrade to version 6.3.2 or 5.19.11 which fixes the issue.
Critical [CVE-2025-30177 +1] Improper input validation vulnerability in Apache Camel Undertow component
Improper input validation vulnerability in Apache Camel Undertow component. This issue affects Apache Camel: from 4.11.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. UndertowEndpoint defaulted its headerFilterStrategy field to the base HttpHeaderFilterStrategy and pushed that instance into the UndertowHttpBinding it creates lazily, overwriting the UndertowHeaderFilterStrategy that DefaultUndertowHttpBinding installs in its own constructor. Unless a deployment supplied a custom binding or an explicit headerFilterStrategy, the undertow-specific filtering therefore never executed on endpoint-configured routes: the strategy object was constructed and immediately replaced before it could be consulted. The consequence is that the legacy websocket. Exchange-header prefix was not filtered at the undertow transport boundary in either direction, so an undertow HTTP consumer mapped inbound wire headers of that form onto the Exchange, where an undertow WebSocket producer reads them as dispatch directives and can be made to deliver to a peer other than the one the route selected; and header names that undertow itself does not accept were mapped onto the Exchange rather than being skipped. Rest DSL consumers were never affected, because UndertowComponent assigns UndertowRestHeaderFilterStrategy explicitly, which extends the undertow strategy.
Critical [CVE-2026-55993 +1] Improper input validation vulnerability in Apache Camel Atmosphere Websocket component
Improper input validation vulnerability in Apache Camel Atmosphere Websocket component. This issue affects Apache Camel: from 4.0.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. The camel-atmosphere-websocket producer selects which connected WebSocket peers a message is delivered to through Exchange headers, and the string values of those headers sat outside the Camel namespace: websocket.connectionKey and websocket.connectionKey.list, along with websocket.sendToAll, websocket.eventType and websocket.errorType. WebsocketEndpoint extends ServletEndpoint and so inherits HttpHeaderFilterStrategy, which filters only the Camel and camel prefixes; the dotted names therefore fell outside the filtered namespace and were admitted in both directions by every HTTP-family consumer. In a route bridging an HTTP consumer into an atmosphere-websocket producer, an external sender could supply the list header and take over the producer's dispatch decision. WebsocketProducer.process tests the list header before the single-key header, so an injected value discarded the recipient the route had selected: a notification intended for one connected client could be suppressed, or delivered instead to a different client whose connection key the sender knows.
Critical [CVE-2026-66906] Relative path traversal vulnerability in Apache Camel Azure Storage Blob component
Relative path traversal vulnerability in Apache Camel Azure Storage Blob component. This issue affects Apache Camel: from 4.0.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. The camel-azure-storage-blob component can download an Azure Storage blob to the local filesystem through its download BlobToFile operation, writing into the directory named by the fileDir endpoint option, which is documented as usable from both the producer and the consumer. BlobOperations.download BlobToFile built the local target by joining fileDir with the remote blob name exactly as the Azure SDK reported it (new File(fileDir, client.getBlobName())) and passed the result straight to the SDK download call, with no lexical normalization and no check that the resolved location stayed inside fileDir. The blob name is not route-controlled data: the consumer enumerates the container in BlobConsumer.createBatchExchangesFromContainer, which lists blobs and creates one exchange per entry from BlobItem.getName() verbatim, applying no name filtering by default. A blob name containing parent-directory segments therefore resolved to a location outside the configured fileDir, letting anyone able to influence the names present in the consumed container cause Camel to create or overwrite a file at a location of their choosing, with the privileges of the Camel process.
High [CVE-2026-66908] Improper Authentication vulnerability in Apache Camel Platform HTTP Main component
Improper Authentication vulnerability in Apache Camel Platform HTTP Main component. This issue affects Apache Camel: from 4.8.0 before 4.22.0. The camel-main embedded HTTP server can protect its endpoints with JWT authentication, configured through authenticationEnabled together with the JWT keystore properties. JWTAuthenticationConfigurer.buildJwtOptions returned null when neither jwtIssuer nor jwtAudience was configured, and the caller then skipped the JWTAuthOptions.setJWTOptions call entirely, so the Vert.x JWTAuth instance was built from the keystore alone. The result was that inbound tokens were checked only for signature and expiry: the iss and aud claims were not validated at all. Nothing signalled this - the server started normally and reported no warning - so a deployment configured the documented way silently enforced less than the operator believed it had enabled, and the component documentation itself presented signature and expiry checking as the default with issuer and audience as an optional extra. Both the application server and the management server were affected, because the omission was in each of the two configureAuthentication paths. Any unexpired token signed by any key the configured keystore trusts was therefore accepted, regardless of which issuer minted it or which audience it was intended for.
High [CVE-2026-66907] Relative path traversal vulnerability in Apache Camel Google Storage component
Relative path traversal vulnerability in Apache Camel Google Storage component. This issue affects Apache Camel: from 4.0.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. The camel-google-storage consumer downloads Google Cloud Storage objects to the local filesystem when the download FileName option is set. That option is documented as a folder or a filename, and when its value contains no expression token the consumer builds the local destination by appending the object name to it: evaluateFileExpression sets the Exchange file-name header to the remote object name and evaluates download FileName + "/${file:name}". The ${file:name} token returns the file-name header verbatim, unlike ${file:onlyname}, which applies FileUtil.stripPath to it. The resulting string was passed directly to new File(result) and blob.download To(file.toPath()) with no lexical normalization and no check that the destination stayed inside the configured directory. The object name is not route-controlled data: the consumer lists the bucket, iterates every returned blob and creates one exchange per object from blob.getBlobId().getName() verbatim, and the filter option that could restrict those names is not applied at all unless it has been explicitly set.
