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 AT 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.
