An authenticated user with low privileges can exploit this vulnerability by sending an oversized subject_token JSON Web Token (JWT) to the TokenEndpoint. When the token exceeds a 4000-character limit, it is silently dropped, causing the system to fall back to client credentials. This allows the user to gain the permissions of the client&#39;s service account, leading to privilege escalation.</p> <p><strong>Affected:</strong> Red Hat build of Keycloak 26.4, Red Hat build of Keycloak 26.4.13, Red Hat build of Keycloak 26.6, Red Hat build of Keycloak 26.6.3</p> <p>A flaw was found in Keycloak.
