CVE-2026-3190
March 26, 2026
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.
