# Patch Next advisory brief: CVE-2022-36094

Advisory: XWiki Platform Web Parent POM vulnerable to XSS in the attachment history
IDs: CVE-2022-36094, GHSA-mxf2-4r22-5hq9
Record: https://patchnext.com/advisories/cve-2022-36094 (revision 1, source checked 26 Oct 2026, 16:01 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.xwiki.platform:xwiki-platform-web 14.3-rc-1, 13.10.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-web: affected >= 1.0, < 13.10.6; >= 14.0, < 14.3-rc-1; fixed in 13.10.6, 14.3-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-web: check the installed version with your package manager.

## 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 org.xwiki.platform:xwiki-platform-web.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-mxf2-4r22-5hq9 (GitHub-reviewed advisory GHSA-mxf2-4r22-5hq9 lists affected ranges: Maven org.xwiki.platform:xwiki-platform-web >=1.0 =14.0 <14.3-rc-1)
