CVE-2026-3190
|
| Summary | Keycloak: Missing Role Enforcement on UMA 2.0 Permission Ticket Endpoint Leads to Information Disclosure 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. |
