Contact Form 7 <= 6.0.5 - Order Replay Vulnerability

Improper Validation of Integrity Check Value
CVE CVE-2025-3247
CVSS Medium (5.3)
Publicly Published April 15, 2025
Last Updated April 16, 2025
Researcher Asaf Mozes
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.
