EPSS

• CVE-2026-24126: 0.52% estimated exploitation activity in the next 30 days; percentile 44.14 (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 The SSH management console did not validate the passed input while adding the SSH host key, which could lead to an argument injection to ssh-add. Patches https://github.com/WeblateOrg/weblate/pull/17722 Workarounds Properly limit access to the management console. References This issue was reported to us by alexb616 via HackerOne.

# Patch Next advisory brief: CVE-2026-24126

Advisory: Weblate has an argument injection in management console
IDs: CVE-2026-24126, GHSA-33fm-6gp7-4p47
Record: https://patchnext.com/advisories/cve-2026-24126 (revision 2, source checked 26 Oct 2026, 13:36 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: weblate 5.16.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI weblate: affected < 5.16.0; fixed in 5.16.0

## 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.
