A vulnerability has been identified in Keycloak's administrative services, allowing an attacker with 'manage-clients' privileges to exploit various methods.

The attacker can obtain tokens assigned with 'realm-admin' roles, enabling them to escalate privileges and potentially access sensitive resources that should remain protected.
