Name of the Vulnerable Software and Affected Versions SemanticMediaWiki versions 3.1.0 through 7.3.0

Description A reflected cross-site scripting issue exists where unauthenticated attackers can inject scripts via the unescaped default parameter in the JsonResultPrinter function. By luring victims to a specially crafted 'Special:Ask' link containing a zero-result query and the request type parameter set to 'special page', attackers can execute JavaScript within the wiki origin to steal session cookies or Cross-Site Request Forgery (CSRF) tokens.

Recommendations Update SemanticMediaWiki to version 7.3.1 or later.
