CVE-2026-3190: Red Hat Build Of Keycloak

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
