Subject: MediaWiki Extensions and Skins Security Release Supplement (1.31.8/1.33.4/1.34.2)


With the security/maintenance release of MediaWiki 1.31.8/1.33.4/1.34.2 [0], we would also like to provide this supplementary announcement of MediaWiki extensions and skins with now-public Phabricator tasks, security patches and backports [1]:

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 or file a security task within Phabricator [3].
