GHSA-4vvp-x9h2-x2vf
GHSA-4vvp-x9h2-x2vf is a security vulnerability in public. O3 Security confirms whether GHSA-4vvp-x9h2-x2vf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Path Traversal in public
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.
publicnpmDescription
All versions of public are vulnerable to Path Traversal. This vulnerability allows an attacker to access files outside the webroot since it allows symlink navigation in the URL.
Recommendation
No fix is currently available. Do not use public in production or consider using an alternative module until a fix is made available.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for public. 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.
Remediation status
No patched version of public has shipped for GHSA-4vvp-x9h2-x2vf yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-4vvp-x9h2-x2vf 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-4vvp-x9h2-x2vf. 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-4vvp-x9h2-x2vf in your dependencies?
O3 detects GHSA-4vvp-x9h2-x2vf across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
