The Wikimedia Security Team recommends updating these extensions and/or
skins to the current master branch or relevant, supported release branch
[2] as soon as possible. Some of the referenced Phabricator tasks above
_may_ still be private. Unfortunately, when security issues are reported,
sometimes sensitive information is exposed and since Phabricator is
historical, we cannot make these tasks public without exposing this
sensitive information. If you have any additional questions or concerns
regarding this update, please feel free to contact security(a)wikimedia.org
or file a security task within Phabricator [3].

I would like to announce the release of MediaWiki 1.31.11 and 1.35.1!
These releases also serve as a maintenance release for these branches.
Numerous fixes have been backported into 1.35, including some for PHP 8.0
support (though we are not declaring full PHP 8.0 support yet).
T268894 doesn't apply to MediaWiki 1.31, as the code was added in 1.35.
Also, only one of the two fixes of T268938 apply to MediaWiki 1.31, as the
code was not added until MediaWiki 1.33.
While tarballs have already been uploaded, git tags will follow later on
today.
An "MediaWiki Extensions Security Release Supplement" email will follow
this one.
== Security fixes ==
* (T268894, CVE-2020-35474) SECURITY: Message
recentchanges-legend-watchlistexpiry can contain raw html.
* (T268917, CVE-2020-35475) SECURITY: Messages userrights-expiry-current
and userrights-expiry-none can contain raw html.
* (T268938, CVE-2020-35478, CVE-2020-35479) SECURITY: BlockLogFormatter can
output raw html.
* (T205908, CVE-2020-35477) SECURITY: Unable to change visibility of log
entries when MediaWiki:Mainpage uses Special:MyLanguage.
* (T120883, CVE-2020-35480) SECURITY: Divergent behavior for contributions
and user pages of hidden users and missing users.

Hi all,
Tomorrow we will be issuing a security and maintenance release to all
supported branches of MediaWiki.
The new releases will be:
- 1.31.11
- 1.35.1
This will resolve 5 issues in MediaWiki core (1 of which isn't applicable
to MediaWiki 1.31 at all), and also includes some fixes previously
committed to git, including minor security and hardening patches along with
bug fixes included for maintenance reasons.
We will make the fixes available in these respective release branches, and
also master. Tarballs will be available for the above mentioned point
releases as well.
A summary of some of the security fixes that have gone into non-bundled
MediaWiki extensions will also follow.
As per the MediaWiki Version lifecycle [1], November 2020 was the scheduled
EOL date for the REL1_34. MediaWiki 1.35.1 will be supported until at least
September 2023, and would be the recommended upgrade path for anyone still
using 1.34.
