CVE-2025-56647

npm @farmfe/core before 1.7.6 is Missing Origin Validation in WebSocket.

MEDIUM 6.5EPSS 0.19%

Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

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.
