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@wikimedia.org or file a security task within Phabricator [3].
