XWiki has no right protection on rollback action

CVE-2024-21648GHSA-xh35-w7wg-95v3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.xwiki.platform:xwiki-platform 15.8-rc-1, 15.5.3; org.xwiki.platform:xwiki-platform-oldcore 14.10.17), 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 The rollback action is missing a right protection: it means that a user can rollback to a previous version of the page to gain rights they don't have anymore. This vulnerability impacts all version of XWiki since rollback action is available. Patches The problem has been patched in XWiki 14.10.16, 15.5.3 and 15.8-rc-1 by ensuring that the rights are checked before performing the rollback. Workarounds There's no workaround for this vulnerability, except paying attention to delete old versions of documents that could allow users to gain more rights.

# Patch Next advisory brief: CVE-2024-21648

Advisory: XWiki has no right protection on rollback action
IDs: CVE-2024-21648, GHSA-xh35-w7wg-95v3
Record: https://patchnext.com/advisories/cve-2024-21648 (revision 1, source checked 26 Oct 2026, 16:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.0)
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 15.8-rc-1, 15.5.3; org.xwiki.platform:xwiki-platform-oldcore 14.10.17. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform: affected >= 15.0-rc-1, < 15.5.3; >= 15.6-rc-1, < 15.8-rc-1; fixed in 15.8-rc-1, 15.5.3
- Maven org.xwiki.platform:xwiki-platform-oldcore: affected >= 1.0, < 14.10.17; fixed in 14.10.17

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform: check the installed version with your package manager.
- 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, 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.
