Moloni < 5.0.14 - Subscriber+ Arbitrary Order Invoice Generation via genInvoice

The Moloni WordPress plugin before 5.0.14 does not perform capability or nonce checks on several of its authenticated AJAX actions, relying only on whether the site holds a stored connection to its external invoicing provider, allowing any authenticated user such as a Subscriber to generate fiscal invoices for arbitrary orders, discard arbitrary orders, and create or modify products and stock.
