GHSA-vh2g-6c4x-5hmp is a critical-severity (CVSS 10) Path Traversal vulnerability in nodebb. O3 Security confirms whether GHSA-vh2g-6c4x-5hmp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Path traversal and code execution via prototype vulnerability
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
nodebbnpmDescription
Impact
Due to the use of the object destructuring assignment syntax in the user export code path, combined with a path traversal vulnerability, a specially crafted payload could invoke the user export logic to arbitrarily execute javascript files on the local disk.
Patches
Patched in v2.8.7
Workarounds
Site maintainers can cherry pick ec58700f6dff8e5b4af1544f6205ec362b593092 into their codebase to patch the exploit.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nodebb. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update nodebb to 2.8.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vh2g-6c4x-5hmp is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-vh2g-6c4x-5hmp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-vh2g-6c4x-5hmp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vh2g-6c4x-5hmp in your dependencies?
O3 detects GHSA-vh2g-6c4x-5hmp across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
