Description
Semantic MediaWiki from 2.5.0 before 7.3.1 contains a stored cross-site scripting vulnerability that allows users with page-edit rights to inject scripts via External identifier property values. Attackers can annotate markup payloads that ExternalIdentifierValue renders unescaped on Special:Browse, executing JavaScript in viewers' sessions, including administrators.
