Summary
A flaw was found in Keycloak's client registration service. A remote attacker, possessing a previously issued Registration Access Token (RAT), could exploit this vulnerability to re-enable a client that an administrator had explicitly disabled.

The primary impact includes unauthorized information disclosure and potential integrity compromise.
