Descriptions

An issue was discovered in lib/Server.js in webpack-dev-server before 3.1.6. Attackers are able to steal developer's code because the origin of requests is not checked by the WebSocket server, which is used for HMR (Hot Module Replacement). Anyone can receive the HMR message sent by the WebSocket server via a ws://127.0.0.1:8080/ connection from any origin.

Se ha descubierto un problema en lib/Server.js en webpack-dev-server en versiones anteriores a la 3.1.6. Los atacantes pueden robar el código del desarrollador porque el origen de las peticiones no es comprobado por el servidor WebSocket, utilizado para HMR (Hot Module Replacement). Cualquiera puede recibir el mensaje HMR enviado por el servidor WebSocket mediante una conexión ws://127.0.0.1:8080/ desde cualquier origen.
