GHSA-jgrh-5m3h-9c5f is a medium-severity (CVSS 5.9) CWE-444 vulnerability in find-my-way. O3 Security confirms whether GHSA-jgrh-5m3h-9c5f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Web Cache Poisoning in find-my-way
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.
find-my-waynpmDescription
This affects the package find-my-way before 2.2.5, from 3.0.0 and before 3.0.5. It accepts the Accept-Version' header by default, and if versioned routes are not being used, this could lead to a denial of service. Accept-Version can be used as an unkeyed header in a cache poisoning attack.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | find-my-way | all versions | 2.2.5 |
| 📦npm | find-my-way | ≥ 3.0.0&&< 3.0.5 | 3.0.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for find-my-way. 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 find-my-way to 2.2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jgrh-5m3h-9c5f 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-jgrh-5m3h-9c5f 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-jgrh-5m3h-9c5f. 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-jgrh-5m3h-9c5f in your dependencies?
O3 detects GHSA-jgrh-5m3h-9c5f across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
