CyberRota Analysis
AI-GeneratedThe Stripe Payment Forms plugin for WordPress versions prior to 8.5.2 is vulnerable due to inadequate verification of payment intent ownership in two unauthenticated AJAX actions, allowing attackers to manipulate payment amounts using a publicly accessible nonce. This flaw can lead to unauthorized changes in payment amounts processed through the Stripe API, potentially resulting in financial loss for merchants. WordPress site administrators using this plugin should prioritize updating to version 8.5.2 or later to mitigate this risk.
Original NVD Description
The Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.2 does not verify that the caller owns the Stripe payment intent referenced by two unauthenticated payment-form AJAX actions, allowing an unauthenticated visitor — using a nonce that is embedded in every public page containing a payment form — to change the amount of a payment intent that the Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.2 then updates server-side through the Stripe API with the store's secret key. An ownership check added in 8.5.0 was applied to only one payment-intent handler, leaving the pricing-recalculation and payment-intent-update actions unprotected against amount manipulation.
