Description
Duplicate Advisory: Keycloak has privilege escalation via improper scope mapping enforcement ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-32h4-44jj-c5vx. This link is maintained to preserve external references. ### Original Description A flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the Keycloak realm.
