Keycloak: Missing Role Enforcement on UMA 2.0 Permission Ticket Endpoint Leads to Information Disclosure

發布日:2026/3/26修改日:2026/4/2

描述

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.
