As a user without script or programming right, create a (non-terminal) document named `" + alert(1) + "` (the quotes need to be part of the name). 1. Edit the class. 1. Add a string property named `"test"`. 1. Edit using the object editor and add an object of the created class 1. Get an admin to open `<xwiki-server>/xwiki/bin/view/%22%20%2B%20alert(1)%20%2B%20%22/?viewer=display&type=object&property=%22%20%2B%20alert(1)%20%2B%20%22.WebHome.test&mode=edit` where `<xwiki-server>` is the URL of your XWiki installation. ### Patches This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0. ### Workarounds We're not aware of any workaround except upgrading. ### References - https://jira.xwiki.org/browse/XWIKI-21810 - https://github.com/xwiki/xwiki-platform/commit/27eca8423fc1ad177518077a733076821268509c
