Description
Impact
It's possible to execute a Velocity script without script right through the document tree.
To reproduce:
- As a user without script right, create a document, e.g., named Nasty Title
- Set the document's title to
$request.requestURI - Click "Save & View"
- Reload the page in the browser
The navigation panel displays a document named with the current URL, showing that the Velocity code has been executed even though the user doesn't have script right.
Patches
This has been patched in XWiki 14.10.7 and 15.2RC1.
Workarounds
A possible workaround is to:
- modify the page XWiki.DocumentTreeMacros
- search for the code
#set ($discard = $translatedDocument.setTitle($translatedDocument.title)) - modify it into
#set ($discard = $translatedDocument.setcomment(''))

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-index-tree-macro, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-index-tree-macro to 14.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-50732 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
