Keycloak: Missing Role Enforcement on UMA 2.0 Permission Ticket Endpoint Leads to Information Disclosure
A flaw was found in Keycloak. The User-Managed Access (UMA) 2.0 Protection API endpoint for permission tickets fails to enforce the uma_protection role check. This allows any authenticated user with a token issued for a resource server client, even without the uma_protection role, to enumerate all permission tickets in the system. This vulnerability partial leads to information disclosure.
