CVE-2026-4636
Red Hat Red Hat build of Keycloak 26.2, Red Hat build of Keycloak 26.2.15, Red Hat build of Keycloak 26.4 취약점
A flaw was found in Keycloak. An authenticated user with the uma_protection role can bypass User-Managed Access (UMA) policy validation. This allows the attacker to include resource identifiers owned by other users in a policy creation request, even if the URL path specifies an attacker-owned resource. Consequently, the attacker gains unauthorized permissions to victim-owned resources, enabling them to obtain a Requesting Party Token (RPT) and access sensitive information or perform unauthorized actions.
