Quick fix

GHSA-p773-8mf4-rjm5 — @farmfe/core: upgrade to the fixed version with the command below.

npm install @farmfe/core@1.7.6

Details

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.
