How to Fix GHSA-5843-9mh5-hhgw
To remediate this vulnerability, upgrade all affected Duplicate Advisory dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install vm2@Latest secure release
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls vm2
How to Check if You Are Affected
To determine whether your Node.js application is affected by GHSA-5843-9mh5-hhgw, inspect your project dependencies using npm:
npm ls vm2
Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The npm ls vm2 command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when a NodeVM is explicitly configured to allow require('https'). The builtin loader wraps host modules in a read-only proxy, but method calls such as Agent.prototype.on() are forwarded to the underlying host object, so sandbox code can register a listener for the agent's 'free' event. When an unrelated host HTTPS request releases a pooled connection, the listener receives the live host request options and the host TLSSocket, allowing sandboxed code to read the host's Authorization header and private destination host/port, attach a data listener to the released socket and read subsequent host response bodies in plaintext, and issue attacker-chosen authenticated requests using the stolen credentials. The issue is fixed in 3.11.7.",
