      "value": "In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto."

Esto permite que los clientes conectados de forma local o remota accedan a temas MQTT a los que no tienen derecho de acceso. Este mismo problema tambi\u00e9n podr\u00eda estar presente en plugins de control de autenticaci\u00f3n/acceso para Mosquitto."
