As published by the source; long descriptions are shortened.

Impact Due to improper neutralization, it was possible to perform cross-site scripting via crafted user and language names. Patches The issues were fixed in the 4.11 release. The following commits are addressing it: f6753a1a1c63fade6ad418fbda827c6750ab0bda 9e19a8414337692cc90da2a91c9af5420f2952f1 22d577b1f1e88665a88b4569380148030e0f8389 Workarounds You can look for crafted user and language names to see if you were affected.

# Patch Next advisory brief: CVE-2022-24710

Advisory: Cross-site Scripting in Weblate
IDs: CVE-2022-24710, GHSA-6jp6-9rf9-gc66
Record: https://patchnext.com/advisories/cve-2022-24710 (revision 3, source checked 26 Oct 2026, 13:27 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.1)
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. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI weblate: affected < 4.11; fixed in 4.11

## 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.
