## What is CVE-2026-15288?

CVE-2026-15288 is a high-severity vulnerability in brainstormforce SureForms – Drag & Drop Contact Form & Form Builder, Payment Form, Survey, Quiz & Calculator, published on 10 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 2.2.1. This is due to the plugin accepting the payment amount directly from user-controlled POST data in the 'create_payment_intent' and 'create_subscription_intent' functions without validating it against the form's configured price. This makes it possible for unauthenticated attackers to modify the payment amount to any arbitrary value when submitting a Stripe payment form, potentially purchasing products or services at significantly reduced prices.

Weakness: CWE-20 (Improper Input Validation)
