Technical details
The vulnerability exists in Supabase PostgREST row-level security (RLS) policies on the public.org_users table. The "Allow org admin to insert" and "Allow org admin to update" policies only check that the caller has admin rights via check_min_rights(), but fail to enforce the required invitation acceptance, RBAC role-binding validation, or anti-escalation checks. An authenticated org admin can directly INSERT or UPDATE org_users rows to add any existing user account with user_right="admin", completely bypassing the /private/accept_invitation flow.
Affected products
- Cap-go capgo.app all
