MediaWiki Improper Input Validation Vulnerability - CVE-2014-5243
MediaWiki before 1.19.18 1.20.x through 1.22.x before 1.22.9 and 1.23.x before 1.23.2 does not enforce an IFRAME protection mechanism for transcluded pages which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.
