Published

Semantic MediaWiki from 4.2.0 before 7.3.1 contains a stored cross-site scripting vulnerability that allows authenticated profile or schema editors to inject HTML through FacetedSearch exploration-link labels. Attackers can store markup in the label, which ExploreListBuilder::buildHTML() passes unescaped to Html::rawElement(), altering the Special:FacetedSearch page and potentially running scripts in viewers' browsers.
