Raven 2.0.0 through 3.0.0 contains a missing authorization vulnerability that allows authenticated users to join invite-only Public workspaces by ignoring the can_only_join_via_invite setting. Attackers with the Raven User role can call the join_workspace method to become persistent members, reading and posting in Public and Open channels.
