SemanticMediaWiki from 3.1.0 before 7.3.1 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject markup through the search parameter of the extended Special:Search profile. Attackers can send visitors crafted URLs using the smw profile with SVG event handlers, which ProfileForm::profile_sheet inserts unescaped into a pre element, executing script in the wiki origin.
