EPSS

• CVE-2023-29507: 0.90% estimated exploitation activity in the next 30 days; percentile 59.68 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact The Document script API returns directly a DocumentAuthors allowing to set any authors to the document, which in consequence can allow subsequent executions of scripts since this author is used for checking rights. Example of such attack: Patches The problem has been patched in XWiki 14.10 and 14.4.7 by returning a safe script API. Workarounds There no easy workaround apart of upgrading.

# Patch Next advisory brief: CVE-2023-29507

Advisory: org.xwiki.platform:xwiki-platform-oldcore makes Incorrect Use of Privileged APIs with DocumentAuthors
IDs: CVE-2023-29507, GHSA-pwfv-3cvg-9m4c
Record: https://patchnext.com/advisories/cve-2023-29507 (revision 1, source checked 26 Oct 2026, 16:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.1)
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. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-oldcore: affected >= 14.5, < 14.10; >= 14.4.1, < 14.4.7; fixed in 14.10, 14.4.7

## 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-pwfv-3cvg-9m4c (GitHub-reviewed advisory GHSA-pwfv-3cvg-9m4c lists affected ranges: Maven org.xwiki.platform:xwiki-platform-oldcore >=14.5 =14.4.1 <14.4.7)
