GHSA-hmpr-c9rf-qcrf: Duplicate Advisory Incomplete Nodejs.* Symbol Filtering Lets Vulnerability
HIGHGHSA-hmpr-c9rf-qcrf is a HIGH (CVSS 6.8) incomplete nodejs.* symbol filtering lets vulnerability (CWE-669: Incorrect Resource Transfer Between Spheres) affecting Duplicate Advisory libraries in the npm ecosystem. The issue involves incomplete nodejs.* symbol filtering lets sandbox override host webstream state checks. Remediation is available in the latest vendor maintenance releases.

Security Impact
CVSS: 6.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N).
How to Fix GHSA-hmpr-c9rf-qcrf
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 releaseRun the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls vm2How to Check if You Are Affected
To determine whether your Node.js application is affected by GHSA-hmpr-c9rf-qcrf, inspect your project dependencies using npm:
npm ls vm2Analyze 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.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-669: Incorrect Resource Transfer Between Spheres, where the product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource. In Duplicate Advisory, 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.

This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions 3.11.4 through 3.11.6 incompletely filter Node.js registered internal symbols across the sandbox boundary. The extraction filters in lib/setup-sandbox.js and the cross-realm symbol checks and write traps in lib/bridge.js use a fixed list of known dangerous registered symbols that omits nodejs.stream.disturbed and nodejs.stream.errored, which are exposed on host WebStream prototypes on newer Node.js releases (validated on Node.js v25.8.0). When the embedder exposes a host WebStream object and the host stream/web module to the sandbox, sandbox code can obtain the real host symbols via Object.getOwnPropertySymbols(streamWeb.ReadableStream.prototype) and use them as write keys on host stream objects, corrupting host-visible stream state — for example making stream.Readable.isDisturbed() return false for an already-consumed stream. This can bypass host logic that relies on Node's public stream-state helpers to enforce one-shot body consumption, reject errored streams, or decide whether a stream is safe to hand to another component. It is not a host code-execution primitive in the reported proof of vulnerability. This is an incomplete fix for the earlier nodejs.* symbol filtering issue. Fixed in vm2 3.11.7.",
