Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Various date messages returned by Language::userDate are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This impacts wikis where a group has the editinterface but not the editsitejs user right. This vulnerability is fixed in 3.3.1.
