# Patch Next advisory brief: CVE-2023-29520

Advisory: XWiki Platform vulnerable to page render failure due to broken translations
IDs: CVE-2023-29520, GHSA-9jq5-xwqw-q8j3
Record: https://patchnext.com/advisories/cve-2023-29520 (revision 1, source checked 26 Oct 2026, 16:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
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-localization-source-wiki 14.10.1, 14.4.8, 13.10.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-localization-source-wiki: affected >= 4.3-milestone-2, < 13.10.11; >= 14.0-rc-1, < 14.4.8; >= 14.5, < 14.10.1; fixed in 13.10.11, 14.10.1, 14.4.8

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-localization-source-wiki: 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-localization-source-wiki.
- 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-9jq5-xwqw-q8j3 (GitHub-reviewed advisory GHSA-9jq5-xwqw-q8j3 lists affected ranges: Maven org.xwiki.platform:xwiki-platform-localization-source-wiki >=4.3-milestone-2 =14.0-rc-1 =14.5 <14.10.1)
