CHANNEL_GetLabel() devuelve estas etiquetas sin sanear, y se renderizan a través de hprintf255() en más de 15 ubicaciones en src/httpserver/http_fns.c sin codificación HTML. Un atacante con acceso al bróker MQTT (comúnmente sin autenticar en implementaciones reales) puede establecer una etiqueta de canal que contenga una carga útil [script_tag] que se ejecuta cuando cualquier usuario ve el panel web del dispositivo."
