| Description | Capgo (capgo.app) exposes the legacy membership table public.org_users directly through Supabase PostgREST. The table's row-level security policies "Allow org admin to insert" and "Allow org admin to update" only verify that the caller has admin rights in the target organization (public.check_min_rights('admin', ...)); they do not require a pending invitation in tmp_users, acceptance of an invite token via /private/accept_invitation, any action by the target user, or the membership/role-consistency and anti-escalation checks enforced by the RBAC role-binding path. As a result, an authenticated user who is an admin of an organization can INSERT or UPDATE org_users rows directly to add any existing public.users account as an active member of that organization with user_right="admin", bypassing the invitation and role-assignment workflow entirely. In testing, an account with no prior access to the organization or its apps could, after such a direct insert, read the organization and app and pass check_min_rights. All versions are affected and no patch was available at the time of publication. | |
