GHSA-hv99-mxm5-q397

HIGHFix: WeblateOrg/weblate@5db3a2a

GHSA-hv99-mxm5-q397 is a high-severity (CVSS 7.7) Path Traversal vulnerability in weblate. O3 Security confirms whether GHSA-hv99-mxm5-q397 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

🐍weblate

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

The ZIP download feature didn't verify downloaded file and it could follow symlinks outside the repository.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for weblate. 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 weblate to 5.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hv99-mxm5-q397 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-hv99-mxm5-q397 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-hv99-mxm5-q397. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
