CVE-2014-5243: Input Validation

First published: Fri Aug 22 2014(Updated: )

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.
