Description
npm @farmfe/core before 1.7.6 is Missing Origin Validation in WebSocket. The development (hot module reloading) server does not validate origin when connecting to a WebSocket client. This allows attackers to surveil developers running Farm who visit their webpage and steal source code that is leaked by the WebSocket server.
