FluentCart customers can control other customers' subscriptions
FluentCart before 1.4.0 fails to verify that a subscription identifier belongs to the authenticated customer in several payment-method operations. A customer who learns another subscription identifier can change its payment method, cancel it or re-bind it, crossing the account ownership boundary. The WPScan CNA record does not disclose the endpoint paths, identifier parameter, ownership-check function or payment providers affected.

Technical description
The FluentCart A New Era of eCommerce WordPress plugin before 1.4.0 does not verify that a subscription belongs to the requesting customer in several of its payment-method endpoints, allowing any authenticated customer to act on another customer's subscription (changing its payment method, or cancelling and re-binding it) when they know the target subscription identifier.
