Description: GrowChief through 0.3.0 contains a missing authorization vulnerability in the getAllUsers handler that allows any authenticated user to list users across all organizations because the IsSuperAdmin guard is absent. Attackers with a self-registered low-privilege account can send an empty or short search value to GET /users/all-users to enumerate user ids, emails, names and organization IDs of every tenant.
