GHSA-7p7c-pvvx-2vx3
hyper-staticfile's improper validation of Windows paths could lead to directory traversal attack
Blast Radius
hyper-staticfile🦀hyper-staticfileReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Path resolution in hyper-staticfile didn't correctly validate Windows paths, meaning paths like /foo/bar/c:/windows/web/screen/img101.png would be allowed and respond with the contents of c:/windows/web/screen/img101.png. Thus users could potentially read files anywhere on the filesystem.
This only impacts Windows. Linux and other unix likes are not impacted by this.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🦀crates.io | hyper-staticfile | all versions | 0.9.2 |
| 🦀crates.io | hyper-staticfile | ≥ 0.10.0-alpha.1&&< 0.10.0-alpha.2 | 0.10.0-alpha.2 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for hyper-staticfile. 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 hyper-staticfile to 0.9.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7p7c-pvvx-2vx3 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-7p7c-pvvx-2vx3 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-7p7c-pvvx-2vx3. 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-7p7c-pvvx-2vx3 in your dependencies?
O3 detects GHSA-7p7c-pvvx-2vx3 across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
