Summary
Red Hat Security Advisory: Red Hat build of Keycloak 26.2.5 Images Security Update

Notes

Topic
New images are available for Red Hat build of Keycloak 26.2.5 and Red Hat build of Keycloak 26.2.5 Operator, running on OpenShift Container Platform
Details
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 26.2.5 clusters. This erratum releases new images for Red Hat build of Keycloak 26.2.5 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: * XStream: XStream is vulnerable to a Denial of Service attack due to stack overflow from a manipulated binary input stream (CVE-2024-47072) * Keycloak hostname verification (CVE-2025-3501)

Unlike moderate vulnerabilities, which may require specific conditions or limited privileges, this flaw enables remote attackers to forcefully terminate services by crafting malicious input, impacting system availability.
