Discourse is an open-source discussion platform. Prior to version 2.8.4 in the stable branch and version 2.9.0.beta5 in the beta and tests-passed branches, banner topic data is exposed on login-required sites. This issue is patched in version 2.8.4 in the stable branch and version 2.9.0.beta5 in the beta and tests-passed branches of Discourse. As a workaround, one may disable banners.
