GHSA-pv4c-p2j5-38j4 is a critical-severity (CVSS 10) CWE-425 vulnerability in url-parse. O3 Security confirms whether GHSA-pv4c-p2j5-38j4 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Open Redirect in url-parse
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.
url-parsenpmDescription
Versions of url-parse before 1.4.3 returns the wrong hostname which could lead to Open Redirect, Server Side Request Forgery (SSRF), or Bypass Authentication Protocol vulnerabilities.
Recommendation
Update to version 1.4.3 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | url-parse | ≥ 1.0.0&&< 1.4.3 | 1.4.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for url-parse. 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 url-parse to 1.4.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pv4c-p2j5-38j4 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-pv4c-p2j5-38j4 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-pv4c-p2j5-38j4. 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-pv4c-p2j5-38j4 in your dependencies?
O3 detects GHSA-pv4c-p2j5-38j4 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
