What is CVE-2025-3479?
CVE-2025-3479 is a medium-severity vulnerability in wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder, published on 17 Apr 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
