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 secur...@wikimedia.org or file a security task within Phabricator [3].
Note: The SecurePoll Extension had other enhancements that were related to the
security bug [4] but did not address the security concerns directly. See
Phabricator [5] for more information.
