CVE-2025-3479: Wpmudev Forminator Forms

Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Wpmudev Forminator Forms: before 1.42.1 (fixed in 1.42.1)
