Description
Lotus through 0.10.2 contains an authorization bypass vulnerability in ChangeUserOrganizationView.post that allows authenticated users to join any organization by supplying its UUID. Self-registered attackers who know another organization's UUID can send a POST request to /app/switch_organization/ to access that tenant's data and billing configuration.
