Description
Red Hat has released security updates for the Red Hat build of Keycloak 26.2.13 images used in OpenShift Container Platform. The update addresses two security vulnerabilities: improper invitation token validation allowing unauthorized organization registration (CVE-2026-1529) and incorrect ownership checks in the /uma-policy/ endpoint (CVE-2025-14778). These issues could impact authentication and authorization processes within Keycloak deployments. The update is provided as new container images aligning with the standalone product release for on-premise or private cloud deployments.
