# Patch Next advisory brief: CVE-2008-0780

Advisory: MoinMoin Cross-site scripting (XSS) vulnerability
IDs: CVE-2008-0780, GHSA-53wj-6m7w-j6mj
Record: https://patchnext.com/advisories/cve-2008-0780 (revision 2, source checked 26 Oct 2026, 13:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: moin 1.6.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI moin: affected >= 1.5, <= 1.5.8; >= 1.6, < 1.6.1; fixed in 1.6.1

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