Description

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, `sep` was inserted verbatim into HTML cell joins. This made it possible to inject HTML through the separator value. Version 7.2.0 fixes the issue.
