GHSA-265q-28rp-chq5 is a high-severity (CVSS 7.5) CWE-331 vulnerability in node-uuid. O3 Security confirms whether GHSA-265q-28rp-chq5 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Insecure Entropy Source - Math.random() in node-uuid
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.
node-uuidnpmDescription
Affected versions of node-uuid consistently fall back to using Math.random as an entropy source instead of crypto, which may result in guessable UUID's.
Recommendation
Update to version 1.4.4 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | node-uuid | all versions | 1.4.4 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-uuid. 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 node-uuid to 1.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-265q-28rp-chq5 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-265q-28rp-chq5 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-265q-28rp-chq5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is GHSA-265q-28rp-chq5 in your dependencies?
O3 detects GHSA-265q-28rp-chq5 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
