What it is

Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages. Versions starting in 3.1.0 and prior to 7.0.0 insert the unsanitized value of a data attribute into the DOM as HTML, allowing for stored XSS through wikitext. Version 7.0.0 patches the issue.
