EPSS

• CVE-2023-29210: 1.19% estimated exploitation activity in the next 30 days; percentile 68.06 (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 Any user with view rights on commonly accessible documents including the notification preferences macros can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the user parameter of the macro that provide the notification filters. These macros are used in the user profiles and thus installed by default in XWiki. A proof of concept exploit is If this creates files inside /tmp, the installation is vulnerable. Patches The vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10. Workarounds The issue can be fixed by patching the code in the affected macros that are contained in XWiki documents as shown in the patch for this issue.

# Patch Next advisory brief: CVE-2023-29210

Advisory: org.xwiki.platform:xwiki-platform-notifications-ui Eval Injection vulnerability
IDs: CVE-2023-29210, GHSA-p9mj-v5mf-m82x
Record: https://patchnext.com/advisories/cve-2023-29210 (revision 1, source checked 26 Oct 2026, 16:11 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-notifications-ui 14.10, 14.4.7, 13.10.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-notifications-ui: affected >= 13.2-rc-1, < 13.10.11; >= 14.0-rc-1, < 14.4.7; >= 14.5, < 14.10; fixed in 14.10, 14.4.7, 13.10.11

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-notifications-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-notifications-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.
