CVE-2026-3190

Published: Mar 26, 2026

Modified: Apr 2, 2026

PUBLISHED

CVSS v3.1

4.3

MEDIUM

Description

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.
