Semantic MediaWiki from 3.1.0 before 7.3.1 contains a reflected cross-site scripting vulnerability in the Special:SMWAdmin ID lookup that allows unauthenticated attackers to inject markup through the unescaped id parameter. Attackers can lure an smw-admin administrator into opening a crafted lookup link, bypassing the auto-satisfied edit-token check, to execute script and perform privileged actions in the administrator's session.
