EPSS

• CVE-2023-35166: 62.17% estimated exploitation activity in the next 30 days; percentile 99.18 (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 any wiki content with the right of the TipsPanel author by creating a tip UI extension. To reproduce: Add an object of type UIExtensionClass Set "Extension Point ID" to org.xwiki.platform.help.tipsPanel Set "Extension ID" to org.xwiki.platform.user.test (needs to be unique but otherwise doesn't matter) Set "Extension Parameters" to Set "Extension Scope" to "Current User". Click "Save & View" Open the "Help.TipsPanel" document at <xwiki-host/xwiki/bin/view/Help/TipsPanel where <xwiki-host is the URL of your XWiki installation and press refresh repeatedly. The groovy macro is executed, after the fix you get an error instead. Patches This has been patched in XWiki 15.1-rc-1 and 14.10.5. Workarounds There are no known workarounds for it.

# Patch Next advisory brief: CVE-2023-35166

Advisory: XWiki Platform vulnerable to privilege escalation (PR) from account through TipsPanel
IDs: CVE-2023-35166, GHSA-h7cw-44vp-jq7h
Record: https://patchnext.com/advisories/cve-2023-35166 (revision 1, source checked 26 Oct 2026, 16:17 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
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-help-ui 15.1-rc-1, 14.10.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-help-ui: affected >= 8.1-milestone-1, < 14.10.5; >= 15.0-rc-1, < 15.1-rc-1; fixed in 14.10.5, 15.1-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-help-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-help-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-h7cw-44vp-jq7h (GitHub-reviewed advisory GHSA-h7cw-44vp-jq7h lists affected ranges: Maven org.xwiki.platform:xwiki-platform-help-ui >=8.1-milestone-1 =15.0-rc-1 <15.1-rc-1)
