Discourse is an open source discussion platform. Prior to version 3.0.6 of the stable
branch and version 3.1.0.beta7 of the beta
and tests-passed
branches, more users than permitted could be created from invite links. The issue is patched in version 3.0.6 of the stable
branch and version 3.1.0.beta7 of the beta
and tests-passed
branches. As a workaround, use restrict to email address invites.
