EPSS

• CVE-2022-23915: 3.10% estimated exploitation activity in the next 30 days; percentile 87.77 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2022-23915

Advisory: Improper Neutralization of Special Elements used in a Command ('Command Injection') in Weblate
IDs: CVE-2022-23915, GHSA-3872-f48p-pxqj
Record: https://patchnext.com/advisories/cve-2022-23915 (revision 2, source checked 25 Oct 2026, 00:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: weblate 4.11.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI weblate: affected < 4.11.1; fixed in 4.11.1

## Suggested inspection (read-only)
- `python -m pip show weblate`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on weblate.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-3872-f48p-pxqj (OSV record GHSA-3872-f48p-pxqj lists affected ranges: PyPI weblate >=0 <4.11.1 (fixed))
