EPSS

• CVE-2023-30628: 3.60% estimated exploitation activity in the next 30 days; percentile 89.47 (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.

Kiwi TCMS is an open source test management system. In kiwitcms/Kiwi v12.2 and prior and kiwitcms/enterprise v12.2 and prior, the `changelog.yml` workflow is vulnerable to command injection attacks because of using an untrusted `github.head_ref` field. The `github.head_ref` value is an attacker-controlled value. Assigning the value to `zzz";echo${IFS}"hello";#` can lead to command injection. Since the permission is not restricted, the attacker has a write-access to the repository. Commit 834c86dfd1b2492ccad7ebbfd6304bfec895fed2 of the kiwitcms/Kiwi repository and commit e39f7e156fdaf6fec09a15ea6f4e8fec8cdbf751 of the kiwitcms/enterprise repository contain a fix for this issue.

# Patch Next advisory brief: CVE-2023-30628

Advisory: PYSEC-2023-273
IDs: CVE-2023-30628, GHSA-cw6r-6ccx-5hwx
Record: https://patchnext.com/advisories/cve-2023-30628 (revision 1, source checked 24 Oct 2026, 04:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: kiwitcms 12.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI kiwitcms: affected < 12.3; fixed in 12.3

## Suggested inspection (read-only)
- `python -m pip show kiwitcms`: 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 kiwitcms.
- 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.
