mediawiki/semantic-media-wiki is vulnerable to Cross-Site Scripting (XSS)

mediawiki/semantic-media-wikiTL;DR
Several Semantic MediaWiki special pages render request-controlled error text as raw HTML. Query-error messages on Special:Ask and Special:FacetedSearch, and the invalid-subject message on Special:Browse, are derived from user-supplied input and passed to error-box output without sufficient escaping. Percent-encoded angle brackets can survive the message-encoding step and are reflected as live markup in the browser of a user who follows a crafted link. The fix applies HTML escaping to the reflected error and subject text before it is rendered.
