Description
Impact
User without the right to view documents can deduce their existence by repeated Livetable queries.
Reproduction steps
- Restrict "view" access to
Sandbox.TestPage3by setting an explicit view right for admins - As a user who is not an admin, open
<server>/bin/get/XWiki/LiveTableResults?outputSyntax=plain&classname=&collist=doc.title%2Cdoc.location%2Cdoc.content&doc.title=Sandbo&doc.location=Sandbox.TestPage3&doc.content=dummy&limit=0where<server>is the URL of your XWiki installation.
Expect Result:
No results are displayed as the user doesn't have view rights on Sandbox.TestPage3.
Actual Result:
The result
{
"reqNo": null,
"matchingtags": {},
"tags": [],
"totalrows": 1,
"returnedrows": 0,
"offset": 1,
"rows": [
{
"doc_viewable": false,
"doc_fullName": "obfuscated"
}
]
}
is displayed.
This reveals that a document Sandbox.TestPage3 exists (we explicitly searched for this name) which has a title containing "Sandbo" and a content containing "dummy". By starting with a single letter and then iteratively extending the match, the full content of the title/content or XObject properties can be discovered. Several tests can be combined in a single request to use binary search to narrow down the actual match from a list of possible characters/words. If the used alphabet is known and smaller than 128 distinct characters, it is possible to discover one character with 7 requests. Alternatively, frequencies of words and word pairs (2-gram frequencies) can be used to first guess whole words and only resort to guessing individual characters if none of the predicted words match, allowing a much faster recovery of the textual content. As it also depends on the content how easy the attack is and how much recovered content would be a "successful" attack, it is hard to quantify how many requests are necessary.
Patches
The issue has been patched in XWiki 14.6RC1, 13.10.8, and 14.4.3, the response is not properly cleaned up of obfuscated entries.
Workarounds
The patch for the document XWiki.LiveTableResultsMacros can be manually applied or a XAR archive of a patched version can be imported, on versions >= 12.10.11, >= 13.9-rc-1, and >= 13.4.4.

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-livetable-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.
Fix
Update org.xwiki.platform:xwiki-platform-livetable-ui to 13.10.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p2x4-6ghr-6vmq is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-p2x4-6ghr-6vmq 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-p2x4-6ghr-6vmq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-p2x4-6ghr-6vmq in your dependencies?
O3 detects GHSA-p2x4-6ghr-6vmq across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
