A flaw was found in the installation provider and client registration endpoints of the Keycloak identity management service. A realm administrator with only the read-only view-clients role can access the active primary secret of any confidential client, which should normally be restricted. This exposed secret can be used to impersonate the client and gain unauthorized access to its associated service account permissions.
