# Patch Next advisory brief: CVE-2022-4638

Advisory: collective.contact.widget is vulnerable to cross-site scripting
IDs: CVE-2022-4638, GHSA-5pqf-rvm7-3wgw
Record: https://patchnext.com/advisories/cve-2022-4638 (revision 3, source checked 26 Oct 2026, 13:16 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: collective-contact-widget 1.13. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI collective-contact-widget: affected < 1.13; fixed in 1.13

## Suggested inspection (read-only)
- `python -m pip show collective-contact-widget`: 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 collective-contact-widget.
- 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.
