EPSS

• CVE-2023-29524: 75.69% estimated exploitation activity in the next 30 days; percentile 99.52 (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 It's possible to execute anything with the right of the Scheduler Application sheet page. To reproduce: 1. As a user without script or programming rights, edit your user profile with the object editor and add a new object of type XWiki.SchedulerJobClass (search for "Scheduler") 1. In "Job Script", add the following 1. Click "Save & View" 1. If the job information isn't already displayed (you should see "Job Name", "Job Description", etc.), append ?sheet=XWiki.SchedulerJobSheet to the URL. Patches This has been patched in XWiki 14.10.3 and 15.0 RC1. Workarounds While the fix in the scheduler itself is easy, it relies on the code macro source parameter, which was introduced in 14.10.2 so you have to upgrade to benefit from it.

# Patch Next advisory brief: CVE-2023-29524

Advisory: XWiki Platform vulnerable to code injection from account through XWiki.SchedulerJobSheet
IDs: CVE-2023-29524, GHSA-fc42-5w56-qw7h
Record: https://patchnext.com/advisories/cve-2023-29524 (revision 1, source checked 26 Oct 2026, 16:16 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-scheduler-ui 14.10.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-scheduler-ui: affected >= 2.0.1, < 14.10.3; fixed in 14.10.3

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-scheduler-ui: 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-scheduler-ui.
- 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-fc42-5w56-qw7h (GitHub-reviewed advisory GHSA-fc42-5w56-qw7h lists affected ranges: Maven org.xwiki.platform:xwiki-platform-scheduler-ui >=2.0.1 <14.10.3)
