XWiki Platform: Remote code execution from edit in multilingual wikis via translations

CVE-2024-31983GHSA-xxp2-9c9g-7wmj

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.xwiki.platform:xwiki-platform-localization-source-wiki 15.10-rc-1, 15.5.4, 14.10.20), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact In multilingual wikis, translations can be edited by any user who has edit right, circumventing the rights that are normally required for authoring translations (script right for user-scope translations, wiki admin for translations on the wiki). This can be exploited for remote code execution if the translation value is not properly escaped where it is used. To reproduce, in a multilingual wiki, as a user without script or admin right, edit a translation of AppWithinMinutes.Translations and in the line platform.appwithinminutes.description= add {{async}}{{groovy}}println("Hello from Translation"){{/groovy}}{{/async}} at the end. Then open the app with in minutes home page (AppWithinMinutes.WebHome) in the same locale. If translations are still working and "Hello from Translation" is displayed at the end of the introduction, the installation is vulnerable. Patches This has been patched in XWiki 14.10.20, 15.5.4 and 15.10RC1. Workarounds We're not aware of any workaround except…

# Patch Next advisory brief: CVE-2024-31983

Advisory: XWiki Platform: Remote code execution from edit in multilingual wikis via translations
IDs: CVE-2024-31983, GHSA-xxp2-9c9g-7wmj
Record: https://patchnext.com/advisories/cve-2024-31983 (revision 1, source checked 26 Oct 2026, 16:29 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
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-localization-source-wiki 15.10-rc-1, 15.5.4, 14.10.20. 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, < 14.10.20; >= 15.0-rc-1, < 15.5.4; >= 15.6-rc-1, < 15.10-rc-1; fixed in 15.10-rc-1, 14.10.20, 15.5.4

## 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.
