GHSA-32fq-m2q5-h83g XWiki-Platform vulnerable to stored Cross-site Scripting via the HTML displayer in Live Data

• Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 12.10, < 13.10.10 → fixed in 13.10.10 • Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 14.0, < 14.4.7 → fixed in 14.4.7 • Maven org.xwiki.platform:xwiki-platform-livedata-macro: >= 14.5, < 14.9 → fixed in 14.9

Impact A user without script rights can introduce a stored XSS by using the Live Data macro. For instance: ``` {{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 14.9, 14.4.7, and 13.10.10. Workarounds No known workaround.
