GHSA-hmm7-6ph9-8jf2
HIGHGHSA-hmm7-6ph9-8jf2 is a high-severity (CVSS 8.9) Cross-site Scripting (XSS) vulnerability in org.xwiki.platform:xwiki-platform-livedata-macro. O3 Security confirms whether GHSA-hmm7-6ph9-8jf2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
org.xwiki.platform:xwiki-platform-livedata-macro vulnerable to Basic Cross-site Scripting

org.xwiki.platform:xwiki-platform-livedata-macro☕org.xwiki.platform:xwiki-platform-livedata-macro☕org.xwiki.platform:xwiki-platform-livedata-macroReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
A user without script rights can introduce a stored XSS by using the Live Data macro, if the last author of the content of the page has script rights.
For instance, by adding the LiveData below in the about section of the profile of a user created by an admin.
{{liveData id="movies" properties="title,description"}}
{
"data": {
"count": 1,
"entries": [
{
"title": "Meet John Doe",
"url": "https://www.imdb.com/title/tt0033891/",
"description": "<img onerror='alert(1)' src='foo' />"
}
]
},
"meta": {
"propertyDescriptors": [
{
"id": "title",
"name": "Title",
"visible": true,
"displayer": {"id": "link", "propertyHref": "url"}
},
{
"id": "description",
"name": "Description",
"visible": true,
"displayer": "html"
}
]
}
}

Patches
This has been patched in XWiki 14.10, 14.4.7, and 13.10.11.
Workarounds

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-livedata-macro. 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-livedata-macro to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hmm7-6ph9-8jf2 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-hmm7-6ph9-8jf2 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-hmm7-6ph9-8jf2. 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-hmm7-6ph9-8jf2 in your dependencies?
O3 detects GHSA-hmm7-6ph9-8jf2 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
