MediaWiki 1.36.0-rc.0 is ready for testing

by Tyler Cipriani

I'm pleased to announce the immediate availability of MediaWiki 1.36.0-rc.0, the first release candidate for 1.36.x. Download links are at the end of the e-mail. The tag has been signed and pushed to Git. Please note that MediaWiki 1.36 now requires the PHP internationalization extension, commonly referred to as Intl, ext-intl, or php-intl. This is not a final release, and should not be used for production websites. Known issues are tracked in Phabricator on the release workboard [1]. As always, please try out the release candidate in a test environment and do report any issues that you discover. Please use the #MW-1.36-Release [2] tag in Phabricator when reporting issues specific to this release, to make sure that we find them as quickly as possible. It is expected that MediaWiki 1.36 will become final in May 2021, though the date may slip if blockers are identified.

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].

Maintenance release: 1.31.14

by Sam Reed

The 1.31.14 version fixes an issue with the backports in the 1.31.13 release. The patches linked here need applying on top of the previous patches for 1.31.12. See the previous email for those patches. The full downloads here contain all the previous fixes from the security and maintenance release. Once again, I apologise for the inconvenience of the issues with the previous release. Going forward, we're going to be looking to run more testing on the tarballs (in this case, static analysis via Phan) to hopefully prevent these issues in future. ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.tar.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.zip Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.14.tar.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.14.zip Patch to previous version (1.31.13): https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.patch.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.patch.zip GPG signatures: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.14.tar.gz… https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.14.zip.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.zip.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.14.patch.zip.s… Public keys: https://www.mediawiki.org/keys/keys.html

Security and maintenance release: 1.31.13 / 1.35.2

by Sam Reed

I would like to announce the release of MediaWiki 1.31.13 and 1.35.2! 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). This is the first MediaWiki release where zip files are included too. This is due to some issues with the tarballs for some users with certain extraction applications. Composer 2.0 is also now supported on MediaWiki 1.35.2. MediaWiki also has a new logo as of these releases. T270453 does not apply to MediaWiki 1.31.13, as VisualEditor is not bundled. However the patch will be backported to the 1.31 branch if you use VisualEditor, and you should pick up the update from the usual places. T279451 also does not apply to MediaWiki 1.31.13, as Parsoid is not bundled. If you use the node.js service, it is recommended to update this. T276843 has been fixed in different ways on MediaWiki 1.31.13 and MediaWiki 1.35.2. On the former, we have just disabled the known vulnerable lexers. On 1.35.2, we have upgraded pygments from 2.5.2 to 2.7.4. 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 == * (T270453, CVE-2021-30153) SECURITY: ApiVisualEditor leaks info about hidden users. * (T270713, CVE-2021-30152) SECURITY: Allow user to only apply protection they have right to do so via action=protect. * (T270988, CVE-2021-30155) SECURITY: ContentModelChange: Check that user can create pages. * (T272386, CVE-2021-30159) SECURITY: Non-admin deleted enwiki page in fast double move. * (T276843, CVE-2021-20270, CVE-2021-27291) SECURITY: Various SyntaxHighlight lexers are vulnerable to DoS. * (T277009, CVE-2021-30158) SECURITY: Allow blocked users to access Special:ResetTokens. * (T278014, CVE-2021-30154) SECURITY: Escape mediastatistics-header-* messages on Special:NewFiles. * (T278058, CVE-2021-30157) SECURITY: Escape rcfilters-filter-* messages onChangesList pages. * (T279451, CVE-2021-30458) SECURITY: Parsoid comment fostering allows for inserting mostly arbitrary <meta> tags. == Links to all mentioned tasks == * https://phabricator.wikimedia.org/T270453 * https://phabricator.wikimedia.org/T270713 * https://phabricator.wikimedia.org/T270988 * https://phabricator.wikimedia.org/T272386 * https://phabricator.wikimedia.org/T276843 * https://phabricator.wikimedia.org/T277009 * https://phabricator.wikimedia.org/T278014 * https://phabricator.wikimedia.org/T278058 * https://phabricator.wikimedia.org/T279451 == Release notes == Full release notes for 1.31.13: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_31/RELEASE-NOTES… https://www.mediawiki.org/wiki/Release_notes/1.31 Full release notes for 1.35.2: https://phabricator.wikimedia.org/diffusion/MW/browse/REL1_35/RELEASE-NOTES… https://www.mediawiki.org/wiki/Release_notes/1.35 For information about how to upgrade, see <https://www.mediawiki.org/wiki/Manual:Upgrading> ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.tar.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.zip Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.13.tar.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.13.zip Patch to previous version (1.31.12): https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.patch.gz https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.patch.zip GPG signatures: https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.13.tar.gz… https://releases.wikimedia.org/mediawiki/1.31/mediawiki-core-1.31.13.zip.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.zip.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.31/mediawiki-1.31.13.patch.zip.s… Public keys: https://www.mediawiki.org/keys/keys.html ********************************************************************** Download: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.tar.gz https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.zip Download without bundled extensions: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.2.tar.gz https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.2.zip Patch to previous version (1.35.1): https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.patch.gz https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.patch.zip GPG signatures: https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.2.tar.gz.… https://releases.wikimedia.org/mediawiki/1.35/mediawiki-core-1.35.2.zip.sig https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.tar.gz.sig https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.zip.sig https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.patch.gz.sig https://releases.wikimedia.org/mediawiki/1.35/mediawiki-1.35.2.patch.zip.sig Public keys: https://www.mediawiki.org/keys/keys.html

Security pre-release announcement: 1.31.13 / 1.35.2

by Sam Reed

Hi all, Tomorrow we will be issuing a security and maintenance release to all supported branches of MediaWiki. This has been delayed by a week versus the usual schedule, as making a security last week on 1st April ("April Fools") was deemed not a great idea. The new releases will be: - 1.31.13 - 1.35.2 This will resolve 3 issues in MediaWiki core, 2 issues in bundled extensions (one of which doesn't apply to REL1_31), 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. [1] https://www.mediawiki.org/wiki/Version_lifecycle
