FKIE_CVE-2026-3190

Vulnerability from fkie_nvd - Published: 2026-03-26 19:17 - Updated: 2026-06-17 10:43
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
Summary
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.
