Vendor Workaround
To mitigate this issue, disable the Fine-Grained Admin Permissions (FGAPv2) feature in Keycloak if it is not strictly required. This can typically be done by setting `adminPermissionsEnabled` to `false` in the realm configuration. Disabling FGAPv2 will prevent the exploitation of this flaw by removing the vulnerable functionality. However, this may impact administrative delegation capabilities within Keycloak. A restart or reload of the Keycloak service may be required for the changes to take effect.

| 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. | |
