# Patch Next advisory brief: CVE-2013-4198

Advisory: Plone's authenticated users able to alter their password despite of policy definition
IDs: CVE-2013-4198, GHSA-qjxf-6pr8-j87v
Record: https://patchnext.com/advisories/cve-2013-4198 (revision 3, source checked 26 Oct 2026, 13:22 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: plone 4.3.2, 4.2.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI plone: affected >= 2.1, <= 4.1; >= 4.2, < 4.2.6; >= 4.3, < 4.3.2; fixed in 4.3.2, 4.2.6

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on plone.
- 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.
