Description Murray McAllister 2014-04-28 12:06:50 UTC

The MediaWiki 1.22.6 and 1.21.9 releases fix a cross-site scripting issue. Viewing a malicious page with action=info could lead to arbitrary web script execution in the context of the victim's session.

This issue does not appear to affect any version in EPEL.
