Red Hat build of Keycloak is an integrated sign-on solution, available as a Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat build of Keycloak for OpenShift image provides an authentication server that you can use to log in centrally, log out, and register. You can also manage user accounts for web applications, mobile applications, and RESTful web services. Red Hat build of Keycloak Operator for OpenShift simplifies deployment and management of Keycloak 26.4.4 clusters. This erratum releases new images for Red Hat build of Keycloak 26.4.4 for use within the OpenShift Container Platform cloud computing Platform-as-a-Service (PaaS) for on-premise or private cloud deployments, aligning with the standalone product release. Security fixes: * Unable to restrict access to the admin console (CVE-2025-10939) * Debug default bind address (CVE-2025-11538) * User can refresh offline session even after client's offline_access scope was removed (CVE-2025-12110) * WebAuthn Attestation Statement Verification Bypass (CVE-2025-12150) * Offline Session takeover due to reused Authentication Session ID (CVE-2025-12390)

Red Hat build of Keycloak 26.4.4 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications. Security fixes: * Unable to restrict access to the admin console (CVE-2025-10939) * Debug default bind address (CVE-2025-11538) * User can refresh offline session even after client's offline_access scope was removed (CVE-2025-12110) * WebAuthn Attestation Statement Verification Bypass (CVE-2025-12150) * Offline Session takeover due to reused Authentication Session ID (CVE-2025-12390)

CVE-2025-11538 is a medium-severity vulnerability in Red Hat's build of Keycloak 26.4 where enabling debug mode causes the Java Debug Wire Protocol (JDWP) port to bind to all network interfaces (0.0.0.0) by default. This exposes the debug port to the local network, allowing attackers on the same network segment to attach a remote debugger and execute arbitrary code within the Keycloak JVM. The vulnerability requires no authentication or user interaction but has a high attack complexity due to network access requirements. Exploitation can lead to full compromise of the Keycloak server's confidentiality and integrity. No known exploits are currently reported in the wild. European organizations using this Keycloak version in network environments where debug mode might be enabled are at risk, especially those with sensitive identity and access management deployments.
