Discourse is an open source discussion platform. Prior to version 3.0.4 of the stable branch and version 3.1.0.beta5 of the beta and tests-passed branches, an attacker could use the new topics dismissal endpoint to reveal the number of topics recently created (but not the actual content thereof) in categories they didn’t have access to. This issue is patched in version 3.0.4 of the stable branch and version 3.1.0.beta5 of the beta and tests-passed branches. There are no known workarounds.
