  4. Edit using the object editor and add an object of the created class
  5. 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.
