ZITADEL's Service Users Deactivation not Working

Impact

ZITADEL’s user account deactivation mechanism did not work correctly with service accounts. Deactivated service accounts retained the ability to request tokens, which could lead to unauthorized access to applications and resources.

Workarounds

• Revoke all existing authentication keys associated with the service account
• Rotate the service account’s password
