Real-World Exposure

2 pkgs affected
🦀hyper-staticfile🦀hyper-staticfile

Real-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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for hyper-staticfile, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. 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.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7p7c-pvvx-2vx3 can be triaged on real exposure rather than presence alone.

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

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.
