CVE-2012-4379
MediaWiki before 1.18.5, and 1.19.x before 1.19.2 does not send a restrictive X-Frame-Options HTTP header, which allows remote attackers to conduct clickjacking attacks via an embedded API response in an IFRAME element.
Does this matter?
Lower severity and a low EPSS score (1.45%). Track it; it rarely justifies an emergency change on its own.
