Summary
The FluentCart WordPress plugin before version 1.4.0 does not verify that a subscription belongs to the requesting customer in several payment-method endpoints. This allows any authenticated customer to act on another customer's subscription (changing payment method, cancelling, or re-binding it) when they know the target subscription identifier.
Risk Assessment
The organization is at risk of unauthorized subscription modifications, potentially leading to financial losses and loss of customer trust.
Recommendation
Immediately update the FluentCart plugin to version 1.4.0 or later.
