GHSA-jfgp-674x-6q4p is a medium-severity (CVSS 4.4) CWE-73 vulnerability in weblate. O3 Security confirms whether GHSA-jfgp-674x-6q4p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Weblate vulnerable to improper sanitization of project backups
Real-World Exposure
weblateReal-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
Weblate didn't correctly validate filenames when restoring project backup. It may be possible to gain unauthorized access to files on the server using a crafted ZIP file.
Patches
This issue has been addressed in Weblate 5.6.2 via https://github.com/WeblateOrg/weblate/commit/b6a7eace155fa0feaf01b4ac36165a9c5e63bfdd.
Workarounds
Do not allow project creation to untrusted users.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update weblate to 5.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jfgp-674x-6q4p 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-jfgp-674x-6q4p 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-jfgp-674x-6q4p. 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-jfgp-674x-6q4p in your dependencies?
O3 detects GHSA-jfgp-674x-6q4p across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
