EPSS

• CVE-2013-7061: 1.31% estimated exploitation activity in the next 30 days; percentile 70.79 (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.

Products/CMFPlone/CatalogTool.py in Plone 3.3 through 4.3.2 allows remote administrators to bypass restrictions and obtain sensitive information via an unspecified search API.

# Patch Next advisory brief: CVE-2013-7061

Advisory: Plone Privilege escalation through exposed underlying API
IDs: CVE-2013-7061, GHSA-4vr8-r7qr-fpvq
Record: https://patchnext.com/advisories/cve-2013-7061 (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 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: products-cmfplone 4.3.3; plone 4.3.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI products-cmfplone: affected >= 3.3, < 4.3.3; fixed in 4.3.3
- PyPI plone: affected >= 3.3b1, < 4.3.3; fixed in 4.3.3

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