Contact Form 7, CVE-2025-3247

CVE, Research URL: CVE-2025-3247
Home page URL: Security reports for Contact Form 7
Application: Contact Form 7
Published on: Apr 16, 2025
Research 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.
Affected versions: Min -, max 6.0.6.
Status: vulnerable
