What is CVE-2026-2729?
CVE-2026-2729 is a medium-severity missing authorization vulnerability in wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder, published on 5 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Forminator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.52.0. This is due to the plugin not properly verifying that a user is authorized to perform an action when processing attacker-supplied Stripe PaymentIntent identifiers in the public payment flow. This makes it possible for unauthenticated attackers to submit high-value paid forms as completed by reusing a previously succeeded low-value Stripe PaymentIntent, resulting in underpayment/payment bypass conditions.
