CVE-2026-2733

Org.keycloak/keycloak-services: keycloak: missing check on disabled client for docker registry protocol

A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.

Org.keycloak/keycloak-services: keycloak: unauthorized modification of unmanaged user attributes by administrators

A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications.

Org.keycloak/keycloak-services: improper enforcement of disabled identity provider in identitybrokerservice (authentication bypass)

A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.

Org.keycloak.protocol.oidc: keycloak refresh token reuse bypass via toctou race condition

A flaw was found in the Keycloak server during refresh token processing, specifically in the TokenManager class responsible for enforcing refresh token reuse policies. When strict refresh token rotation is enabled, the validation and update of refresh token usage are not performed atomically. This allows concurrent refresh requests to bypass single-use enforcement and issue multiple access tokens from the same refresh token. As a result, Keycloak’s refresh token rotation hardening can be undermined.

Keycloak: org.keycloak/keycloak-services: keycloak: privilege escalation via manage-clients permission

A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.

Org.keycloak.protocol.oidc: blind server-side request forgery (ssrf) in keycloak oidc dynamic client registration via jwks_uri

A flaw was identified in Keycloak’s OpenID Connect Dynamic Client Registration feature when clients authenticate using private_key_jwt. The issue allows a client to specify an arbitrary jwks_uri, which Keycloak then retrieves without validating the destination. This enables attackers to coerce the Keycloak server into making HTTP requests to internal or restricted network resources. As a result, attackers can probe internal services and cloud metadata endpoints, creating an information disclosure and reconnaissance risk.

Keycloak: cli option for encrypted jgroups ignored

A vulnerability was found in Keycloak. The environment option `KC_CACHE_EMBEDDED_MTLS_ENABLED` does not work and the JGroups replication configuration is always used in plain text which can allow an attacker that has access to adjacent networks related to JGroups to read sensitive information.

Undertow: url-encoded request path information can be broken on ajp-listener

A vulnerability was found in Undertow, where URL-encoded request paths can be mishandled during concurrent requests on the AJP listener. This issue arises because the same buffer is used to decode the paths for multiple requests simultaneously, leading to incorrect path information being processed. As a result, the server may attempt to access the wrong path, causing errors such as "404 Not Found" or other application failures. This flaw can potentially lead to a denial of service, as legitimate resources become inaccessible due to the path mix-up.

Resteasy-netty4-cdi: resteasy-netty4: resteasy-reactor-netty: http request smuggling leading to client timeouts in resteasy-netty4

A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk.

Eap: oidc app attempting to access the second tenant, the user should be prompted to log

A flaw was found in Red Hat Enterprise Application Platform 8. When an OIDC app that serves multiple tenants attempts to access the second tenant, it should prompt the user to log in again since the second tenant is secured with a different OIDC configuration. The underlying issue is in OidcSessionTokenStore when determining if a cached token should be used or not. This logic needs to be updated to take into account the new "provider-url" option in addition to the "realm" option. EAP-7 does not provide the vulnerable provider-url configuration option in its OIDC implementation and is not affected by this flaw.

A flaw was found in` JwtValidator.resolvePublicKey` in JBoss EAP, where the validator checks jku and sends a HTTP request. During this process, no whitelisting or other filtering behavior is performed on the destination URL address, which may result in a server-side request forgery (SSRF) vulnerability.

A flaw was found in codeplex-codehaus. A directory traversal attack (also known as path traversal) aims to access files and directories stored outside the intended folder. By manipulating files with "dot-dot-slash (../)" sequences and their variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on the file system, including application source code, configuration, and other critical system files.
