Summary

Invite bypasses user approval in Discourse

Details

Discourse is an open source platform for community discussion. Prior to version 2.8.4 on the stable branch and 2.9.0beta5 on the beta and tests-passed branches, inviting users on sites that use single sign-on could bypass the must_approve_users check and invites by staff are always approved automatically. The issue is patched in Discourse version 2.8.4 on the stable branch and version 2.9.0.beta5 on the beta and tests-passed branches. As a workaround, disable invites or increase min_trust_level_to_allow_invite to reduce the attack surface to more trusted users.
