Description
Semantic MediaWiki versions from 3.0.0 up to but not including 7.4.1 contain a stored cross-site scripting (XSS) vulnerability in the DataTables integration. This flaw allows users with page-edit rights to inject HTML entity-encoded markup into data-search or data-filter cell attributes, which can execute scripts in the browsers of viewers, including administrators.
