uhub did not have this security bug since the hub did not advertise support for the UCMD extension, but the message was still correctly relayed as specified in the protocol specification. However, this commit adds support for the UCMD extension, but only to the extent that uhub will advertise it and uhub will also drop any such CMD message generated by a client and will (currently) never issues a CMD message by itself.
