Keycloak vulnerable to Improper Client Certificate Validation for OAuth/OpenID clients
When a Keycloak server is configured to support mTLS authentication for OAuth/OpenID clients, it does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client and therefore access data that belongs to other clients.
