Name of the Vulnerable Software and Affected Versions Semantic MediaWiki versions 3.0.0 through 7.4.0

Description A stored cross-site scripting issue exists in the 'Special:Ask' endpoint when using the ElasticStore backend. Users with edit permissions can inject scripts via unescaped native result and score set output. This occurs when an attacker stores markup within a Text property or subobject name and lures a victim, such as an administrator, to a specially crafted 'Special:Ask' link to execute the script within the victim's session.

Recommendations Update Semantic MediaWiki to version 7.4.1 or later.
