Описание
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.

The issue was rated as Moderate. This flaw in Keycloak allows information disclosure due to improper role enforcement in the UMA 2.0 Protection API. An authenticated user with a token issued for a resource server client, even without the uma_protection role, can enumerate all permission tickets in the system.
