# Patch Next advisory brief: CVE-2022-41937

Advisory: Missing Authorization in Filter Stream Converter Application of XWiki-platform
IDs: CVE-2022-41937, GHSA-q6jp-gcww-8v2j
Record: https://patchnext.com/advisories/cve-2022-41937 (revision 1, source checked 26 Oct 2026, 16:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
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-filter-ui 14.6-rc-1, 14.4.3, 13.10.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-filter-ui: affected < 13.10.8; >= 14.0.0, < 14.4.3; >= 14.5.0, < 14.6-rc-1; fixed in 14.6-rc-1, 13.10.8, 14.4.3

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-filter-ui: 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-filter-ui.
- 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
