CVE-2017-1000482GHSA-859j-668v-mrr6

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (products-cmfplone 5.1.0, 5.0.10, 4.3.17; plone 5.1.0, 4.3.16), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2017-1000482

Advisory: Products.CMFPlone XSS in profile home_page property
IDs: CVE-2017-1000482, GHSA-859j-668v-mrr6
Record: https://patchnext.com/advisories/cve-2017-1000482 (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: Vendor fix available; fixed versions by package: products-cmfplone 5.1.0, 5.0.10, 4.3.17; plone 5.1.0, 4.3.16. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI products-cmfplone: affected < 4.3.17; >= 5.0.0, < 5.0.10; >= 5.1a1, < 5.1.0; fixed in 5.0.10, 5.1.0, 4.3.17
- PyPI plone: affected >= 2.5a1, < 4.3.16; >= 5.0a1, < 5.1.0; fixed in 5.1.0, 4.3.16

## 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.
