High [CVE-2026-71559] Deserialization of Untrusted Data vulnerability in the Go implementation of Apache Fory allows an attacker to cause a denial of service by supplying crafted data containing malformed type metadata, which triggers an uncaught panic
Deserialization of Untrusted Data vulnerability in the Go implementation of Apache Fory allows an attacker to cause a denial of service by supplying crafted data containing malformed type metadata, which triggers an uncaught panic. This issue affects Apache Fory: from 0.16.0 before 1.5.0. Users of other language implementations are not affected. Users are recommended to upgrade to version 1.5.0, which fixes the issue.
High [CVE-2025-49506] APR-util versions 1.6.3 (and earlier) function apr_password_validate was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel timing attack particularly on platforms without crypt such as Windows, BeOS, NetWare, or Android
APR-util versions 1.6.3 (and earlier) function apr_password_validate() was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel timing attack particularly on platforms without crypt() such as Windows, BeOS, NetWare, or Android. Users are recommended to upgrade to version 1.6.4, which fixes this issue.
High [CVE-2026-34501] Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility redis client
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility redis client. This issue affects Apache Portable Runtime Utility: from 1.6.0 through 1.6.3. Users are recommended to upgrade to version 1.6.4, which fixes the issue.
High [CVE-2026-34502] Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility memcached client This issue affects Apache Portable Runtime Utility: from 1.3.0 through 1.6.3
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility memcached client This issue affects Apache Portable Runtime Utility: from 1.3.0 through 1.6.3.
High [CVE-2026-57818] race condition in JCacheCodeDataProvider allows an attacker to redeem a single authorization code multiple times via concurrent requests, resulting in the issuance of multiple distinct, valid access tokens
A race condition in JCacheCodeDataProvider allows an attacker to redeem a single authorization code multiple times via concurrent requests, resulting in the issuance of multiple distinct, valid access tokens. Users are recommended to upgrade to versions 4.2.3, 4.1.8 or 3.6.12, which fix this issue.
High [CVE-2026-68481] In Apache CXF's DefaultEncryptingOAuthDataProvider, revoked access tokens still decrypt successfully, and TokenIntrospectionService reports active:true
In Apache CXF's DefaultEncryptingOAuthDataProvider, revoked access tokens still decrypt successfully, and TokenIntrospectionService reports active:true. The same applies to refresh tokens. This violates the RFC stipulations that 'The authorization server MUST invalidate the token.' and 'introspection of a revoked token MUST return {"active":false}'. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
High [CVE-2026-65432] Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities
Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any or referenced from that top-level WSDL is handed off to WSDL4J, which does not disable DOCTYPE declarations or external entities. As a result, the protections applied to the top-level document do not extend to imported documents, leaving imported WSDL/XSD content vulnerable to XML External Entity (XXE) attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
High [CVE-2026-57817] Apache CXF RP: The OpenID Connect Core 1.0 specification mandates that the RP MUST validate the `c_hash` parameter when operating in the Hybrid Flow
The OpenID Connect Core 1.0 specification mandates that the RP MUST validate the `c_hash` parameter when operating in the Hybrid Flow. If an Apache CXF RP is integrated with a non-compliant or misconfigured Identity Provider (IdP) that omits the `c_hash`, the RP becomes vulnerable to Authorization Code Substitution/Injection attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
High [CVE-2026-50645 +1] incomplete fix for CVE-2026-50645 means that it is still possible to perform a denial of service attack on Apache CXF by sending a message with many attachment headers
An incomplete fix for CVE-2026-50645 means that it is still possible to perform a denial of service attack on Apache CXF by sending a message with many attachment headers. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
High [CVE-2026-57819] Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the "maxFormParameterCount" configuration option
Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the "maxFormParameterCount" configuration option. However, no default limit is set which may lead to denial of service attacks when processing requests with very large numbers of form parameters. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue by using a default limit of 500 parameters.
High [CVE-2026-54225] Apache CXF allows to control the maximum attachment size via the "attachment-max-size"
Apache CXF allows to control the maximum attachment size via the "attachment-max-size". Prior to Apache CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service attack is possible if the user doesn't explicitly set the limit. Users should update to Apache CXF 4.2.3 or 4.1.8 or 3.6.12 which fixes this problem by imposing a default attachment size limit of 50mb.
High [CVE-2026-60023] Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Answer
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.1. Deleted or pending answers could be retrieved by unauthorized users through the single-answer read path when the parent question remained visible, exposing answer content that should not have been accessible. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
High [CVE-2026-48911] Insufficient Verification of Data Authenticity vulnerability in Apache Answer
Insufficient Verification of Data Authenticity vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.1. A missing authorization check in the external-login email binding flow allows unauthenticated attackers to take over arbitrary user accounts by tricking victims into clicking a crafted confirmation link. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
High [CVE-2026-48834] Improper Handling of Length Parameter Inconsistency vulnerability in Apache Answer
Improper Handling of Length Parameter Inconsistency vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.1. Unauthenticated attackers can cause a denial of service via a specially crafted Accept-Language header that triggers excessive CPU consumption during parsing. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
