[Chris Steipp]

I would like to announce the release of MediaWiki 1.21.2, 1.20.7 and
1.19.8. These releases fix 3 security related bugs that could affect users
of MediaWiki. Download links are given at the end of this email.

* Mozilla, and other developers, reported a full path disclosure in
MediaWiki, when an invalid language is specified in ResourceLoader
<https://bugzilla.wikimedia.org/show_bug.cgi?id=46332>

* An internal review found several API modules allowed anti-CSRF tokens to
be accessed via JSONP.

* Andreas Peetz reported an issue with the MediaWiki API where an invalid
property name could be used for XSS with older versions of Internet
Explorer.

Additionally, the following extensions have been updated to fix security
issues:
