# Patch Next advisory brief: CVE-2023-29208

Advisory: org.xwiki.platform:xwiki-platform-oldcore vulnerable to data leak through deleted documents
IDs: CVE-2023-29208, GHSA-4f8g-fq6x-jqrr
Record: https://patchnext.com/advisories/cve-2023-29208 (revision 1, source checked 26 Oct 2026, 16:11 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
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-oldcore 14.10, 14.4.7, 13.10.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-oldcore: affected >= 1.2-milestone-1, < 13.10.11; >= 14.0-rc-1, < 14.4.7; >= 14.5, < 14.10; fixed in 14.10, 14.4.7, 13.10.11

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-oldcore: 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-oldcore.
- 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-4f8g-fq6x-jqrr (GitHub-reviewed advisory GHSA-4f8g-fq6x-jqrr lists affected ranges: Maven org.xwiki.platform:xwiki-platform-oldcore >=1.2-milestone-1 =14.0-rc-1 =14.5 <14.10)
