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].

Hi all, On Thursday we will be issuing a security and maintenance release to all supported branches of MediaWiki. The new releases will be: - 1.35.10 - 1.38.6 - 1.39.3 This will resolve one issue in MediaWiki core, and two issues in bundled extensions along with bug fixes included for maintenance reasons. This includes various patches for PHP 8.0, PHP 8.1 and PHP 8.2 support. We will make the fixes available in the respective release branches (plus 1.40 which is currently in alpha candidate status) and master in git. 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 later. As a reminder, 1.38 is due to become end of life (EOL) in June 2023. 1.38.7 (due in June 2023 on the usual release cadence) is expected to be the last release for this branch. It is recommended to upgrade to 1.39 (the next LTS after 1.35). [1] https://www.mediawiki.org/wiki/Version_lifecycle
