How to Fix CVE-2025-56647

To remediate this vulnerability, upgrade all affected @farmfe/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@farmfe/core fixed: 1.7.6 
npm install @farmfe/core@1.7.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @farmfe/core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-56647, inspect your project dependencies using npm:

npm ls @farmfe/core

Analyze the terminal output to locate any version of @farmfe/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.6), your application is affected.

Note: The npm ls @farmfe/core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1385: Missing Origin Validation in WebSockets, where the product uses a websocket, but it does not properly verify that the source of data or communication is valid. In @farmfe/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
