CVE-2026-3190

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-3190
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.

Summary
  • (es) Se encontró una falla en Keycloak. El endpoint de la API de protección de User-Managed Access (UMA) 2.0 para tickets de permiso no aplica la verificación del rol 'uma_protection'. Esto permite que cualquier usuario autenticado con un token emitido para un cliente de servidor de recursos, incluso sin el rol 'uma_protection', enumere todos los tickets de permiso en el sistema. Esta vulnerabilidad conduce parcialmente a la revelación de información.
