Vulnerabilidad · Publicado 25/09/2026
El plugin Knit Pay para WordPress, utilizado para procesar pagos con Cashfree, Instamojo, Razorpay y PayPal, contiene una vulnerabilidad de escalada de privilegios (CVSS 8.8) en versiones hasta 9.6.1.0. La falla permite a atacantes modificar roles de usuario a través de campos de entrada de Gravity Forms, comprometiendo el acceso administrativo. Afecta directamente a tiendas en línea, plataformas de suscripción y negocios digitales en LATAM que dependen de estos gateways de pago.
The Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.6.1.0. This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field — configured via the feed's `user_role_field_id` — and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` — the currently authenticated submitter's own user ID — making any authenticated form submitter an eligible exploitation target.
