Semantic MediaWiki from 3.0.0 before 7.3.1 contains a stored cross-site scripting vulnerability that allows users with page-edit rights to inject HTML through Keyword-typed property values rendered unescaped on Special:Browse. Attackers can annotate a Keyword property with an event-handler payload that executes JavaScript in viewers' sessions, including administrators, to read tokens and perform actions.
