# CVE-2026-111579: Forminator Forms 1.58.0 - 1.58.3 - Unauthenticated Privilege Escalation via Paid Registration Form When Stripe Gateway Unavailable

Status: published. Published: 2026-11-11. Updated: 2026-11-11.

The Forminator Forms  WordPress plugin before 1.58.4 does not enforce payment on the server side when a form's configured payment gateway is unavailable, allowing unauthenticated visitors to complete a payment-gated User Registration form without paying and be assigned the form's configured role, up to administrator, after the gateway has been connected and later disconnected.
