Description

Impact

It's possible for a user to execute anything with the right of the author of the XWiki.ClassSheet document.

Steps to Reproduce:

  1. Edit your user profile with the object editor and add an object of type DocumentSheetBinding with value Default Class Sheet
  2. Edit your user profile with the wiki editor and add the syntax {{async}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}
  3. Click "Save & View"

Expected result:

An error is displayed as the user doesn't have the right to execute the Groovy macro.

Actual result:

The text "Hello from groovy!" is displayed at the top of the document.

Patches

This has been patched in XWiki 15.0-rc-1 and 14.10.4.

Workarounds

There are no known workarounds for it.

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-test-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-test-ui to 14.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-36fm-j33w-c25f 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-36fm-j33w-c25f 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-36fm-j33w-c25f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
