Vulnerability Title
Keycloak: keycloak: information disclosure via improper role enforcement in uma 2.0 protection api
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
