Description

Impact

Any user with view rights 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 UIX parameters

A proof of concept exploit is to log in, add an XWiki.UIExtensionClass xobject to the user profile page, with an Extension Parameters content of:

order=100
label={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
icon=icon:pencil
target=XWiki.username

Then, navigating to PanelsCode.ApplicationsPanelConfigurationSheet (i.e., <xwiki-host>/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet where <xwiki-host> is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see Hello from groovy! displayed on the screen.

Patches

The vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1

Workarounds

The issue can be fixed by editing the PanelsCode.ApplicationsPanelConfigurationSheet wiki page and making the same modifications as shown in the patch for this issue.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-panels-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update org.xwiki.platform:xwiki-platform-panels-ui to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qxjg-jhgw-qhrv is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-qxjg-jhgw-qhrv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-qxjg-jhgw-qhrv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
