A vulnerability in the Keycloak Admin REST API allows delegated administrators with view-only permissions to access rotated client secrets stored in a secure vault. This occurs due to improper boundary enforcement, exposing sensitive credentials that should remain protected. The issue affects Keycloak versions prior to 26.7.2. Red Hat has released patches addressing this flaw in their build of Keycloak 26.6.6. No known exploits are reported in the wild.

Multiple critical security vulnerabilities have been identified in Red Hat build of Keycloak 26.6.6 images used within OpenShift Container Platform. These include privilege escalation via a TOCTOU vulnerability, unauthenticated account takeover, leakage of rotated client secrets, predictable account-linking hashes enabling account takeover, and unauthorized disclosure of hidden group metadata. Red Hat has released updated container images to address these issues for on-premise and private cloud deployments.

Red Hat has issued a critical security update for its build of Keycloak 26.6.6, addressing multiple vulnerabilities including privilege escalation via a TOCTOU flaw, unauthenticated account takeover, information disclosure, and predictable hashes enabling account takeover. The update fixes five CVEs affecting authentication and authorization components. Users are advised to back up their installations before applying the update.

A flaw was found in the Keycloak Admin REST API, which is used to manage security realms and clients. The issue occurs when the system processes requests for rotated client secrets that are stored in a secure vault. Due to improper boundary enforcement, a delegated administrator with view-only permissions can retrieve the actual resolved secret instead of the vault placeholder, leading to the exposure of sensitive credentials.
