MediaWiki does not require PHP's register_globals setting since version 1.2.0. If you have it on, turn it *off* if you can.

- Correction for API path fix, broken in 1.10.3
January 23, 2008
This is a security update to the Winter 2007 quarterly release. A potential XSS injection vector affecting api.php only for Microsoft Internet Explorer users has been closed.
To work around the vulnerability without upgrading, you may disable the API if you don't need it:
- $wgEnableAPI = false;
Not vulnerable versions:
- 1.12 or later
- 1.11 >= 1.11.1
- 1.10 >= 1.10.3
- 1.9 >= 1.9.5
- 1.8 any version (if $wgEnableAPI has been left off)
- 1.11 <= 1.11.0rc1
- 1.10 <= 1.10.2
- 1.9 <= 1.9.4
- 1.8 any version (if $wgEnableAPI has been switched on)
MediaWiki 1.7 and below are not affected as they do not include the API functionality, however the BotQuery extension is similarly vulnerable unless updated to the latest SVN version.
September 10, 2007
This is a security fix update to the Spring 2007 quarterly release snapshot. A possible HTML/XSS injection vector in the API pretty-printing mode has been found and fixed.
The vulnerability may be worked around in an unfixed version by simply disabling the API interface if it is not in use, by adding this to LocalSettings.php:
- $wgEnableAPI = false;
Not vulnerable versions:
- 1.11 >= 1.11.0
- 1.10 >= 1.10.2
- 1.9 >= 1.9.4
- 1.8 >= 1.8.5
- 1.11 <= 1.11.0rc1
- 1.10 <= 1.10.1
- 1.9 <= 1.9.3
- 1.8 <= 1.8.4 (if $wgEnableAPI has been switched on)
MediaWiki 1.7 and below are not affected as they do not include the faulty function, however the BotQuery extension is similarly vulnerable unless updated to the latest SVN version.
July 13, 2007

April 30, 2007
THIS IS A RELEASE CANDIDATE MADE AVAILABLE FOR TESTING! A FINAL 1.10.0 RELEASE WILL APPEAR WITHIN A FEW DAYS.
MediaWiki is now using a "continuous integration" development model with quarterly snapshot releases. The latest development code is always kept "ready to run", and in fact runs our own sites on Wikipedia.
Release branches will continue to receive security updates for about a year from first release, but nonessential bugfixes and feature developments will be made on the development trunk and appear in the next quarterly release.
Those wishing to use the latest code instead of a branch release can obtain it from source control: Download from SVN
- A new switch $wgCommandLineDarkBg used by maintenance scripts (parserTests.php). It lets you specify if your terminal use a dark background, the colorized output will be made lighter making things easier to read.
- The minimum permissions needed to edit a page in each namespace can now be customized via the $wgNamespaceProtection array. By default, editing pages in the MediaWiki namespace requires "editinterface" permission, as before.
- Allow restriction of autoconfirmed permission by edit count. New global setting $wgAutoConfirmCount (defaulting to zero, naturally).
- Added rate limiter for Special:Emailuser
- Private logs can now be created using $wgLogRestrictions
- (bug 8590) limited HTML is now always enabled ($wgUserHtml = true).

- (bug 8567) Added hook RawPageViewBeforeOutput just before the text is blown out in action=raw, so extensions might influence the output.
- (bug 3446) Add user preference to hide page content below diffs, can be overridden by adding diffonly=1 or diffonly=0 to the URL of the diff page

- (bug 4133) Allow page protections to be made with an expiry date, in the same format as block expiry dates. Existing protections are assumed to be infinite, as are protections made with the new field left blank.
- (bug 8535) Allow certain vertical alignment attributes to be used as image keywords
- (bug 6987) Allow perrow, widths, and heights attributes for <gallery>

PHP sends only 'text/html' by default when the script didn't specify more details, which some inconsiderate browsers consider a license to autodetect the deadly, hard-to-escape UTF-7. This fixes an issue with the Ajax interface error message on MSIE when $wgUseAjax is enabled (not default configuration); this UTF-7 variant on a previously fixed attack vector was discovered by Moshe BA from BugSec: http://www.bugsec.com/articles.php?Security=24

MediaWiki 1.10 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing: http://bugs.php.net/bug.php?id=34879 Upgrade affected systems to PHP 5.1 or higher.
MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
1.10 has several database changes since 1.9, and will not work without schema updates.
If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.
If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading!
See the file UPGRADE for more detailed upgrade instructions.
Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.)
For notes on 1.9.x and older releases, see HISTORY.
Documentation for both end-users and site administrators is currently being built up on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain) :
A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list:
A low-traffic announcements-only list is also available:
It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes.
