CVE-2025-3247: CWE-354 Improper Validation of Integrity Check Value in rocklobsterinc Contact Form 7
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.
AI Analysis
Technical Summary
CVE-2025-3247 is an Order Replay vulnerability in the Contact Form 7 WordPress plugin (rocklobsterinc) affecting all versions up to and including 6.0.5. The issue arises from improper validation of a user-controlled key in the 'wpcf7_stripe_skip_spam_check' function, classified under CWE-354 (Improper Validation of Integrity Check Value). This flaw enables unauthenticated attackers to reuse a single Stripe PaymentIntent multiple times. Although Stripe processes only the first payment, the plugin erroneously sends confirmation emails for each replayed transaction, which may cause administrators to mistakenly fulfill multiple fraudulent orders.
Potential Impact
The vulnerability does not allow direct financial loss via Stripe because only the first payment is processed. However, it impacts integrity by causing the plugin to send multiple successful order emails for a single payment, potentially leading to fraudulent order fulfillment by administrators. There is no confidentiality or availability impact reported.
Mitigation Recommendations
No patch or official fix is currently available for this vulnerability. Users should monitor vendor advisories for updates. Until a fix is released, administrators should be cautious about fulfilling orders solely based on email confirmations from Contact Form 7 when Stripe payments are involved. Additional manual verification of payment status in Stripe is recommended to prevent fraudulent order fulfillment.
