Detailed vulnerability description
The vulnerability allows a remote user to cancel arbitrary Stripe subscriptions.
The vulnerability exists due to improper access control in the StripeYPT test.php debug endpoint when processing user-supplied Stripe webhook-style payloads. A remote user can send a specially crafted payload containing a target subscription ID to cancel arbitrary Stripe subscriptions.
The issue is triggered through the retrieveSubscriptions() method, which cancels a subscription instead of only retrieving it.
