GHSA-3872-f48p-pxqj is a high-severity (CVSS 8.8) CWE-88 vulnerability in weblate. O3 Security confirms whether GHSA-3872-f48p-pxqj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper Neutralization of Special Elements used in a Command ('Command Injection') in Weblate
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 sanitize some arguments passed to Git and Mercurial, which allowed changing their behavior in an unintended way.
Patches
The issues were fixed in the 4.11.1 release. The following commits are addressing it:
- 35d59f1f040541c358cece0a8d4a63183ca919b8
- d83672a3e7415da1490334e2c9431e5da1966842
Workarounds
Instances in which untrusted users cannot create new components are not affected.

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 4.11.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3872-f48p-pxqj 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-3872-f48p-pxqj 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-3872-f48p-pxqj. 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-3872-f48p-pxqj in your dependencies?
O3 detects GHSA-3872-f48p-pxqj across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
