AI-suggested
Until an official fix is available, administrators should be cautious about fulfilling orders based solely on plugin-generated success emails for Stripe payments. Monitoring for unusual order patterns and manual verification of payment status directly through Stripe is recommended.
Description
The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Order Replay in all versions up to, and including, 1.42.0 via the 'handle_stripe_single' function due to insufficient validation on a user controlled key. This makes it possible for unauthenticated attackers to reuse a single Stripe PaymentIntent for multiple transactions. Only the first transaction is processed via Stripe, but the plugin sends a successful email message for each transaction, which may trick an administrator into fulfilling each order.
