• CVE-2023-29207: 1.39% estimated exploitation activity in the next 30 days; percentile 72.41 (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 Livetable Macro wasn't properly sanitizing column names, thus allowing the insertion of raw HTML code including JavaScript. This vulnerability was also exploitable via the Documents Macro that is included since XWiki 3.5M1 and doesn't require script rights, this can be demonstrated with the syntax {{documents id="example" count="5" actions="false" columns="doc.title, before<scriptalert(1)</scriptafter"/}}. Therefore, this can also be exploited by users without script right and in comments. With the interaction of a user with more rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content. Patches This has been patched in XWiki 14.9, 14.4.6, and 13.10.10. Workarounds It is possible to apply the patch to existing installations without upgrading. Only the files skins/flamingo/macros.vm and templates/macros.vm in the web application directory need to be…

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 14.9, 14.4.6, 13.10.10; org.xwiki.platform:xwiki-web-standard 14.9, 14.4.6, 13.10.10; org.xwiki.platform:xwiki-platform-flamingo-skin 14.9, 14.4.6, 13.10.10; org.xwiki.platform:xwiki-platform-flamingo-skin-resources 14.9, 14.4.6, 13.10.10; org.xwiki.platform:xwiki-platform-flamingo 14.9, 14.4.6, 13.10.10; org.xwiki.platform:xwiki-platform-web-templates 14.9, 14.4.6, 13.10.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-web: affected >= 1.9-milestone-2, < 13.10.10; >= 14.0-rc-1, < 14.4.6; >= 14.5, < 14.9; fixed in 14.4.6, 14.9, 13.10.10

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-web: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-web-standard: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-flamingo-skin: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-flamingo-skin-resources: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-flamingo: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-web-templates: 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, org.xwiki.platform:xwiki-web-standard, org.xwiki.platform:xwiki-platform-flamingo-skin, org.xwiki.platform:xwiki-platform-flamingo-skin-resources, org.xwiki.platform:xwiki-platform-flamingo, org.xwiki.platform:xwiki-platform-web-templates.
- 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.
