AI-Generated

The Forminator Forms plugin for WordPress is vulnerable to DOM-Based Reflected Cross-Site Scripting due to inadequate input sanitization and output escaping in the 'error_description' parameter, affecting all versions up to 1.57.0. This flaw allows unauthenticated attackers to inject malicious scripts into pages hosting a Forminator form that utilizes the Stripe Checkout Sessions payment API, potentially compromising user data upon page access. WordPress site administrators using this plugin, particularly those with forms configured for Stripe payments, should prioritize patching to mitigate the risk of exploitation.

Original NVD Description

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to DOM-Based Reflected Cross-Site Scripting via the 'error_description' parameter in all versions up to, and including, 1.57.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability is only triggerable on pages hosting a Forminator form configured to use the Stripe Checkout Sessions payment API, which became the default in 1.56.0.
