EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 91% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
