Medium [CVE-2026-14615] FGAP v2 parent group children endpoint bypasses per-child view permission filter

A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that it requires the attacker to possess a delegated administrator role with specific permissions. Successful exploitation allows an attacker to disclose sensitive group metadata and attributes that should be restricted. The vulnerability's root cause is an improper conditional check in the group retrieval logic that fails to apply permission filters when FGAP v2 is enabled. Weakness: CWE-1220. Affected Red Hat products: Red Hat build of Keycloak 26.4; Red Hat build of Keycloak 26.4.14; Red Hat build of Keycloak 26.6; Red Hat build of Keycloak 26.6.5. Red Hat fixing advisory: RHSA-2026:50847, RHSA-2026:50846, RHSA-2026:50849, RHSA-2026:50848.

Medium [CVE-2026-14614] FGAP v2 client scope assignment bypass via ClientResource

A flaw was found in the ClientResource component of Keycloak's admin services when Fine-Grained Admin Permissions (FGAP) v2 is enabled. This issue allows a delegated administrator, who should only have limited control over specific clients, to attach or remove hidden client scopes that they are not authorized to see or manage. As a result, an attacker could inject unauthorized data or permissions into the security tokens issued to end-users, potentially tricking other applications into granting higher levels of access than intended. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that exploitation requires the attacker to already hold a delegated administrator role with specific client management permissions and knowledge of internal resource identifiers (UUIDs). Successful exploitation allows an attacker to bypass fine-grained authorization boundaries to modify the contents of tokens issued by Keycloak, potentially leading to unauthorized actions in downstream applications. The vulnerability's root cause is a missing authorization check on the referenced client scope during the assignment process in the admin REST API. Weakness: CWE-639. Affected Red Hat products: Red Hat build of Keycloak 26.4; Red Hat build of Keycloak 26.4.14; Red Hat build of Keycloak 26.6; Red Hat build of Keycloak 26.6.5.

Medium [CVE-2026-14613] FGAP v2 role groups endpoint discloses hidden group metadata without group view permission

A vulnerability was discovered in Keycloak's administrative interface that allows certain administrators to see information about groups they shouldn't have access to. When the new Fine-Grained Admin Permissions (FGAP v2) are turned on, an administrator who is allowed to see a specific "role" can also see a list of all groups assigned to that role. The system fails to check if the administrator has permission to see those specific groups. This could allow a restricted administrator to discover "hidden" groups and see their details, such as internal names and custom settings, which might contain sensitive deployment information. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate. While it allows for an unauthorized disclosure of group metadata, it requires the attacker to already possess a delegated administrative role with specific view permissions. The vulnerability is a result of a missing authorization check in the RoleContainerResource component when FGAP v2 is active. Direct access to the hidden groups remains protected; the leak occurs only through the role-to-group mapping enumeration endpoint. Weakness: CWE-1220. Affected Red Hat products: Red Hat build of Keycloak 26.6; Red Hat build of Keycloak 26.6.6. Red Hat fixing advisory: RHSA-2026:56524, RHSA-2026:56523.

Medium [CVE-2026-14612] off-by-one buffer overflows in ipa-otpd oauth2.c during OAuth2 device authorization

Two off-by-one errors in the FreeIPA ipa-otpd daemon's OAuth2 device authorization handler can cause out-of-bounds memory access when processing an oversized response from a configured external OAuth2/OIDC Identity Provider. An attacker who controls or can man-in-the-middle the IdP endpoint may be able to trigger ipa-otpd to write or read one byte past the end of a fixed-size buffer. Exploitation requires FreeIPA to be configured with an external IdP, attacker control or MITM of that IdP, and a user to initiate the OAuth2 device authorization flow. The most likely impact is limited denial of service affecting the ipa-otpd daemon. Red Hat rates this issue as Low impact. We have not identified a path to arbitrary code execution, privilege escalation, or disclosure of Kerberos keys or other IdM secrets. The practical outcome is limited to instability or crash of the ipa-otpd service handling that authentication attempt. Red Hat severity: Low — CVSS 4.2 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L). Weakness: CWE-787. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.

Medium [CVE-2026-8926] Information disclosure via incorrect.netrc password lookup

When asking curl to use a `.netrc` file to find credentials and at the same time specifying a URL with a username(without a password), like `, curl could wrongly get and use the password for *another* user set in the `.netrc` file for that host if such a one exists and there is no match for the specified user. A flaw was found in curl. This could lead to unauthorized information disclosure, as curl might connect using unintended credentials. Red Hat severity: Moderate — CVSS 4.8 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:N/A:N). Weakness: CWE-289.

Medium [CVE-2026-8924] Cookie injection via malicious HTTP server using super cookies

A flaw in curl’s cookie parsing logic allows a malicious HTTP server to set 'super cookies' that bypass the Public Suffix List check. This enables an attacker-controlled origin to inject cookies that curl subsequently scopes and transmits to unrelated third-party domains. Moderate: Red Hat rates this flaw Moderate (CVSS 6.5) compared to CISA's Critical (9.1). The scoring difference is due to two factors: first, exploitation requires the victim's curl to connect using a trailing-dot hostname (e.g.,.), a format that is uncommon in practice and incompatible with TLS SNI; second, the direct impact is cookie injection into outbound requests — not exfiltration of victim data to the attacker. The curl project itself rates this flaw Low severity. Red Hat products that use curl for HTTP communication are affected, but the trailing-dot precondition significantly limits real-world exploitability. This flaw has not been shown to enable impacts beyond session integrity modification. Weakness: CWE-565. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Hardened Images; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4; Red Hat OpenShift Dev Spaces; Red Hat Satellite 6.

Medium [CVE-2026-11856] Information disclosure via incorrect Digest authentication header reuse

Successfully using libcurl to do a transfer to a specific HTTP origin (`hostA`) with **Digest** authentication and then changing the origin to a different one (`hostB`) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the `Authorization:` header field meant for `hostA`, to `hostB`. A flaw was found in curl. This could lead to unintended information disclosure, potentially allowing an attacker to gain unauthorized access to sensitive data. This Moderate-severity flaw in `libcurl` can lead to information disclosure when an application reuses a `libcurl` handle for transfers to different HTTP origins while using Digest authentication. The vulnerability arises from `libcurl` incorrectly sending the authentication header intended for the initial origin to a subsequent, different origin. This could expose sensitive authentication data to an unintended recipient, potentially compromising user credentials or session information.

Medium [CVE-2026-11564] Certificate validation bypass due to incorrect connection reuse

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA material for a later transfer. A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority (CA) trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA material for a subsequent transfer, potentially bypassing intended certificate validation. This Moderate flaw in curl allows a certificate validation bypass. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-295.

Medium [CVE-2026-10536] Use-after-free vulnerability leading to Denial of Service

A use-after-free vulnerability exists in libcurl when an application configures an HTTP/2 stream-dependency tree via `CURLOPT_STREAM_DEPENDS` or `CURLOPT_STREAM_DEPENDS_E`, subsequently invokes `curl_easy_reset()`, and finally terminates the handle with `curl_easy_cleanup()`. During this final cleanup phase, libcurl attempts to access and modify an internal structure that was already freed during the reset operation. This can lead to application crashes, resulting in a Denial of Service (DoS). It occurs when an application specifically configures an HTTP/2 stream-dependency tree and then performs a precise sequence of `curl_easy_reset()` and `curl_easy_cleanup()` operations, attempting to access already freed memory. This vulnerability requires a specific application programming pattern, limiting its exploitability in typical Red Hat deployments. Red Hat severity: Moderate — CVSS 4.7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10.

Medium [CVE-2026-50149] JWT verification bypass allows unauthorized access via HTTPProxy misconfiguration

Contour is a Kubernetes ingress controller using Envoy proxy. In versions 1.23.0 through 1.33.4, when an `HTTPProxy` is configured with incompatible combination of both `.spec.virtualhost.tls.enableFallbackCertificate: true` and `.spec.virtualhost.jwtProviders`, Contour does not reject the configuration. Consequently, requests from clients that do not send TLS SNI or send an unrecognized SNI (one that does not match any `HTTPProxy` FQDN) bypass configured JWT verification and are proxied to upstream services without a valid token. This issue is fixed in Contour v1.33.5. Contour now rejects and marks invalid any `HTTPProxy` resources that combine `.spec.virtualhost.tls.enableFallbackCertificate: true` with `.spec.virtualhost.jwtProviders`. Affected resources will receive a status condition with the error reason `TLSIncompatibleFeatures`. Remove one of the two settings to avoid the invalid configuration. A flaw was found in Contour. When an HTTPProxy is configured with both a fallback certificate and JWT (JSON Web Token) providers, Contour does not properly enforce JWT verification. This allows remote attackers to bypass security checks by sending requests without a valid token, specifically when clients do not provide a TLS Server Name Indication (SNI) or provide an unrecognized SNI.

Medium [CVE-2026-54886] Erlang OTP ssh: Denial of Service via infinite loop in SFTP channel

Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in Erlang OTP ssh (ssh_sftpd module) allows an authenticated SFTP user to render an SFTP channel permanently unresponsive. The handle_data/4 function in ssh_sftpd contains a catch-all clause that accepts channel data of any type. When channel data with a non-zero type code (SSH_MSG_CHANNEL_EXTENDED_DATA) arrives with an empty pending buffer and a payload at or below the SFTP packet size limit, the clause tail-calls itself with identical arguments, creating an infinite loop. The SFTP protocol operates exclusively on normal channel data (type 0). Extended data (non-zero type) is meaningless for SFTP and is never sent by conforming clients. However, the SSH protocol permits any channel participant to send extended data on an open channel, so an authenticated SFTP client can trigger the loop by sending SSH_MSG_CHANNEL_EXTENDED_DATA with any data_type_code and any non-empty payload at or below the size limit. The targeted ssh_sftpd process enters an infinite tail-recursive loop. It never processes another message, its message queue grows without bound, and it can only be stopped by killing the process. Affected products named by the advisory: Red Hat Hardened Images; Red Hat OpenStack Platform 16.2; Red Hat OpenStack Platform 17.1; Red Hat OpenStack Platform 18.0.

Medium [CVE-2026-53422] Erlang OTP ssh: Information disclosure via SFTP REALPATH handler

Observable Response Discrepancy vulnerability in Erlang OTP ssh (ssh_sftpd module) allows an authenticated SFTP user to enumerate the existence of files and directories outside the configured root directory. The SSH_FXP_REALPATH handler in ssh_sftpd calls relate_file_name/3 with Canonicalize=false, unlike every other SFTP operation handler. This allows.. components in the requested path to bypass the is_within_root/2 check without being resolved. The un-canonicalized path then enters resolve_symlinks/2, which walks up the directory tree above the configured root and issues read_link() syscalls on arbitrary filesystem paths. An authenticated SFTP client can exploit this by sending a REALPATH request with a crafted traversal path. The server response differs depending on whether the target path exists on the host filesystem (SSH_FXP_NAME when the path resolves successfully, SSH_FX_NO_SUCH_FILE when it does not). This creates a path-existence oracle that an attacker can use to enumerate the filesystem structure outside the configured root, including the existence of sensitive files, directories, and mount points. The vulnerability leaks only the existence of paths. No file contents, credentials, or write access are obtainable through this issue alone. The information gained may assist further attacks when combined with other vulnerabilities.

Medium [CVE-2026-54431] DPoP verifier accepts malformed proof with private key material

In liboauth2 the Demonstrating Proof-of-Possession (DPoP) verifier accepts a proof whose JSON Web Key (jwk) header contains private key material. RFC 9449 section 4.3 step 7 requires the verifier to reject such a proof but oauth2_token_verify() function returns success for a malformed DPoP proof that embeds the private Elliptic Curve (EC) key in the header. This issue was fixed in version 2.3.0 A flaw was found in liboauth2. This vulnerability could allow an attacker to bypass the intended proof-of-possession mechanism. A flaw in liboauth2's DPoP verifier allows it to accept malformed proofs containing private key material, contrary to RFC 9449. The impact is limited to applications that implement DPoP using liboauth2 and do not perform additional validation.

Medium [CVE-2026-54430] Server-Side Request Forgery allows unauthorized internal network access

liboauth2 is vulnerable to Server-Side Request Forgery in oauth2_jose_jwks_aws_alb_resolve() function. The AWS ALB verifier reads both signer and kid from the unverified JWT header. If signer matches the configured ARN, kid is appended to alb_base_url without URL encoding or path sanitization, and the HTTP GET is issued before signature verification. This allows an attacker to force the server to send a GET request to an attacker-chosen internal path. This issue was fixed in version 2.3.0 An attacker who can present a crafted JWT to an endpoint using AWS ALB verification could force the server to issue GET requests to unintended internal paths, potentially disclosing limited information from internal services. This Moderate flaw in liboauth2 allows for Server-Side Request Forgery (SSRF) when an application uses AWS ALB JWT verification. This requires the vulnerable component to be configured with AWS ALB JWT verification. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N). Weakness: CWE-918.

Medium [CVE-2026-53358] use chan timer to close channels in cleanup_listen

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to close channels in cleanup_listen() l2cap_chan_close() removes the channel from conn->chan_l, which must be done under conn->lock. cleanup_listen() runs under the parent sk_lock, so acquiring conn->lock would invert the established conn->lock -> chan->lock -> sk_lock order. Instead of calling l2cap_chan_close() directly, schedule l2cap_chan_timeout with delay 0 to close the channel asynchronously. The timeout handler already acquires conn->lock and chan->lock in the correct order. The timer is only armed when chan->conn is still set: if it is already NULL, l2cap_conn_del() has already processed this channel (l2cap_chan_del + l2cap_sock_teardown_cb + l2cap_sock_close_cb), so there is nothing left to do. If l2cap_conn_del() races in after the timer is armed, __clear_chan_timer() inside l2cap_chan_del() cancels it; if the timer has already fired, the handler returns harmlessly because chan->conn was cleared. A flaw was found in the Linux kernel's Bluetooth L2CAP (Logical Link Control and Adaptation Protocol) implementation. This vulnerability arises from an incorrect order of acquiring locks during channel cleanup, which could lead to a race condition. This issue could potentially cause instability or unexpected behavior within the Bluetooth subsystem.

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath. Rel check for workingDir and does not account for symlink traversal, so when AllowPathTraversalOnWrite=false an attacker-controlled blob title through ocispec. AnnotationTitle such as out/pwn.txt can follow a workingDir symlink out -> /some/outside/dir and cause pushFile() to create /some/outside/dir/pwn.txt outside workingDir. This issue is fixed in version 2.6.1. A flaw was found in oras-go. The file content store, intended to confine writes to a specified working directory, does not properly account for symbolic link (symlink) traversal. A remote attacker, by providing a specially crafted blob title, could exploit this vulnerability to create files outside the intended working directory. This filesystem boundary bypass allows for arbitrary file creation, potentially leading to unauthorized data modification or system compromise depending on the runtime environment.

Medium [CVE-2026-50163] Information disclosure and arbitrary file access via crafted tarball hardlinks

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link("victim.secret", "/payload.tar.gz/evil_cwd_link") to resolve header. Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname="victim.secret" with io.deis.oras.content.unpack: "true", which can expose or tamper with files such as.env,.git/config,.aws/credentials, and ~/.ssh/config. This issue is fixed in version 2.6.2. An attacker can exploit this vulnerability by providing a specially crafted tarball containing a malicious hardlink. When this tarball is extracted, the hardlink can be manipulated to point to files outside the intended extraction location, specifically within the victim's current working directory. This allows an attacker to read sensitive information from the system, and in some cases, could lead to unauthorized access to critical system files if the component is operating with elevated privileges. A flaw was found in oras-go.

Medium [CVE-2026-48815] Unauthorized certificates accepted due to ignored `certificateOIDs` verification option

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the documented certificateOIDs option in sigstore.verify() is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked and applications relying on certificateOIDs to restrict which certificates may sign artifacts can accept unauthorized certificates. This issue is fixed in version 4.1.1. A flaw was found in sigstore. This allows unauthorized certificates to be accepted, bypassing security policies that rely on specific certificate extension object identifiers (OIDs). As a result, applications that depend on this option for security receive no protection, potentially leading to the acceptance of malicious or untrusted artifacts. Note: The CVSS has been adjusted with AC:H, due to it's low real-world exposure. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N). Weakness: CWE-345.
