Summary

Red Hat build of Keycloak 26.4 and 26.6 are affected. The UserManagedPermissionService does not validate the resourceType field when a user creates a policy, a missing authorization check (CWE-862). An authenticated user with low privileges can create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data.

Description from the CNA

A flaw was found in the UserManagedPermissionService of the Keycloak authorization server. The UMA Protection API, which manages user permissions, fails to validate the resourceType field when a user creates a new policy. This allows an attacker to create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data across the entire realm.
