CyberRota Analysis

AI-Generated

The Stripe Payment Forms by WP Full Pay plugin for WordPress versions prior to 8.5.5 is vulnerable to unauthorized subscription cancellations, as it fails to verify the ownership of subscriptions against the requesting customer-portal session. This flaw allows an authenticated user to cancel subscriptions belonging to other customers if they know the target subscription's identifier, which, while high-entropy and not easily guessable, poses a risk if discovered. WordPress site administrators using this plugin should prioritize updating to version 8.5.5 or later to mitigate this security risk.

Original NVD Description

The Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.5 does not verify that a subscription belongs to the customer bound to the requesting customer-portal session before cancelling it, allowing a user with a confirmed portal session to cancel subscriptions belonging to other customers. Exploitation requires the attacker to know the target subscription's identifier, which is high-entropy and not enumerable through the Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.5.
