• Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 13.10.10, < 13.10.11 → fixed in 13.10.11 • Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 14.4, < 14.4.7 → fixed in 14.4.7 • Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 14.9, < 14.10 → fixed in 14.10

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. ```javascript {{liveData id="movies" properties="title,description"}} { "data": { "count": 1, "entries": [ { "title": "Meet John Doe", "url": "https://www.imdb.com/title/tt0033891/", "description": "" } ] }, "meta": { "propertyDescriptors": [ { "id": "title", "name": "Title", "visible": true, "displayer": {"id": "link", "propertyHref": "url"} }, { "id": "description", "name": "Description", "visible": true, "displayer": "html" } ] } } {{/liveData}} ``` Patches This has been patched in XWiki 14.10, 14.4.7, and 13.10.11. Workarounds No known workaround.
