Contact Form 7 Paypal Stripe Add On
Monthly
Broken access control in Contact Form 7 - PayPal & Stripe Add-on versions 2.5.1 and below allows unauthenticated remote attackers to invoke privileged plugin functionality without authorization, enabling unauthorized modification of plugin state or disruption of payment form behavior. Discovered and disclosed by Patchstack (ENISA EUVD-2026-57898), the flaw is rooted in CWE-862 (Missing Authorization), meaning one or more plugin endpoints or AJAX handlers execute sensitive actions without verifying caller permissions. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Payment bypass in the Contact Form 7 - PayPal & Stripe Add-on for WordPress (all versions up to and including 2.4.9) permits unauthenticated attackers to complete arbitrary pending orders without tendering the required payment amount. The IPN handler correctly authenticates PayPal callbacks via the `cmd=_notify-validate` round-trip, but then blindly trusts the attacker-controlled `invoice` field and passes it to `cf7pp_complete_payment()` without verifying that `mc_gross`, `mc_currency`, or `receiver_email` in the IPN match the stored order values - resulting in full order completion triggered by a minimal real payment. No public exploit code has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, but the direct financial incentive and low attack complexity elevate real-world priority beyond what the medium CVSS score alone implies.
