GHSA-4qcv-qf38-5j3j
MEDIUMUnintentional leakage of private information via cross-origin websocket session hijacking
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.

Impact
Private messages or posts might be leaked to third parties if victim opens the attackers site while browsing nodebb.
Patches
- Patched in v3.1.3
- Backported to v2.x line via v2.8.13
Workarounds
Users can cherry-pick https://github.com/NodeBB/NodeBB/commit/51096ad2345fb1d1380bec0a447113489ef6c359 if they are on v3.x

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 3.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4qcv-qf38-5j3j 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-4qcv-qf38-5j3j 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-4qcv-qf38-5j3j. 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-4qcv-qf38-5j3j in your dependencies?
O3 detects GHSA-4qcv-qf38-5j3j across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
