GHSA-9xw9-pvgv-6p76 is a high-severity (CVSS 7.5) CWE-703 vulnerability in http-proxy. O3 Security confirms whether GHSA-9xw9-pvgv-6p76 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Insufficient Error Handling in http-proxy
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.
http-proxynpmDescription
Affected versions of http-proxy are vulnerable to a denial of service attack, wherein an attacker can force an error which will cause the server to crash.
Recommendation
Update to version 0.7.0 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | http-proxy | all versions | 0.7.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for http-proxy. 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 http-proxy to 0.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9xw9-pvgv-6p76 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-9xw9-pvgv-6p76 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-9xw9-pvgv-6p76. 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-9xw9-pvgv-6p76 in your dependencies?
O3 detects GHSA-9xw9-pvgv-6p76 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
