AI-suggested

According to the Red Hat advisory, no effective mitigation or official fix is currently available that meets criteria for ease of use, applicability, or stability. Users should monitor Red Hat advisories for updates. Until a fix is released, restricting client management permissions and avoiding use of hardcoded-claim mappers in sessionless tokens may reduce risk, but no formal mitigation is provided.

Description

A vulnerability in Keycloak's protocol mapper and identity resolution components allows a client manager with limited permissions to impersonate a realm administrator by manipulating identity claims in sessionless service-account tokens. This occurs because these tokens lack session IDs, causing incorrect identity resolution. Exploitation grants full control over the affected realm.
