npm parcel 2.0.0-alpha and before has an Origin Validation Error vulnerability. Malicious websites can send XMLHTTPRequests to the application's development server and read the response to steal source code when developers visit them. | ||||
| all versions | — | 5 MEDIUM | ||
An issue was discovered in HMRServer.js in Parcel parcel-bundler. 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 connection (with a random TCP port number) from any origin. The random port number can be found by connecting to http://127.0.0.1 and reading the "new WebSocket" line in the source code. | ||||
