CVE-2025-3247 – Stripe PaymentIntent Replay Vulnerability in Contact Form 7 for WordPress

CVE ID : CVE-2025-3247

Published : April 16, 2025, 6:15 a.m. | 27 minutes ago

Description : The Contact Form 7 plugin for WordPress is vulnerable to Order Replay in all versions up to, and including, 6.0.5 via the ‘wpcf7_stripe_skip_spam_check’ 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.

Severity: 5.3 | MEDIUM
