GHSA-5635-9mvj-r6hp
CRITICALGHSA-5635-9mvj-r6hp is a critical-severity (CVSS 9.8) vulnerability in vue-backbone. O3 Security confirms whether GHSA-5635-9mvj-r6hp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in vue-backbone
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
vue-backbonenpmDescription
Version 0.1.2 of vue-backbone contained malicious code. The code when executed in the browser would enumerate password, cvc and cardnumber fields from forms and send the extracted values to https://js-metrics.com/minjs.php?pl=
Recommendation
Remove the package from your environment and evaluate your application to determine whether or not user data was compromised.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | vue-backbone | ≥ 0.1.2&&< 0.1.3 | 0.1.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vue-backbone. 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 vue-backbone to 0.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5635-9mvj-r6hp 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-5635-9mvj-r6hp 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-5635-9mvj-r6hp. 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-5635-9mvj-r6hp in your dependencies?
O3 detects GHSA-5635-9mvj-r6hp across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
