Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages. Prior to version 7.2.0, when headers=plain, table header text was emitted into <th> via a raw HTML path. User-controlled mainlabel content could therefore become executable HTML. Version 7.2.0 fixes the issue.
