The Wikimedia Security Team recommends updating these extensions to the current master branch or supported release branches [3] as soon as possible. As you may have noticed, some of the referenced Phabricator tasks above are still 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, please feel free to contact security(a)wikimedia.org or file a security task within Phabricator.
