17 Apr 2024 — A flaw was found in Keycloak. This issue occurs due to improperly enforcing token types when validating signatures locally. This could allow an authenticated attacker to exchange a logout token for an access token and possibly gain access to data outside of enforced permissions. A bug update is now available for Red Hat build of Keycloak 22.0.10 images running on OpenShift Container Platform. This is an enhancement and security update with Moderate impact rating. • https://access.redhat.com/errata/RHSA-2024:1867 • CWE-273: Improper Check for Dropped Privileges •
