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"
}
]

Affected Products
xwikixwikiDetection & 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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 CVE-2023-29508 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
