CVE-2026-114232 Keycloak-services: keycloak-services: uma protection api resourcetype field not validated — cross-owner resource access
Description
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.
