NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-advanced-compat package and not the keycloak-advanced-compat package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
