Description

SemanticMediaWiki from 3.0.0 before 7.3.1 contains a reflected cross-site scripting vulnerability in Special:Ask, which outputs separator parameters (sep, propsep, valuesep, delim, separator) without HTML escaping in list, category, DSV, and CSV result printers. Unauthenticated attackers can send victims crafted Special:Ask links using request_type=raw or request_type=special_page to execute JavaScript in the wiki's origin, stealing sessions or CSRF tokens.
