GHSA-cf92-gfcw-6v53

LOW

GHSA-cf92-gfcw-6v53 is a low-severity (CVSS 3.5) vulnerability in magic-wormhole. O3 Security confirms whether GHSA-cf92-gfcw-6v53 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Magic Wormhole: receive, with --output pointing at an existing directory can be path-traversed

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Impact

A receiver who specifies "--output <dir>" where that output directory currently exists (as a directory).

Patches

0.24.0 will contain the patch

Workarounds

Ensure local target directories specified by "--output" do not already exist

Resources

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for magic-wormhole. 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.

  2. Fix

    Update magic-wormhole to 0.24.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cf92-gfcw-6v53 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 pinpoints whether GHSA-cf92-gfcw-6v53 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-cf92-gfcw-6v53. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
