Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Semantic MediaWiki versions 7.0.0 up to but not including 7.2.0 are affected by a reflected cross-site scripting flaw in Special:Ask, triggered by a forged, unsigned cursor pagination token whose sort fields are echoed into an error message as raw HTML. No authentication is needed; an attacker who gets a victim to open a crafted link can run script in the victim's browser on the wiki's origin. The fix is to upgrade to version 7.2.0.
