 "title": "SureForms – Contact Form Builder, AI Forms, Payment Form, Survey & Quiz <= 2.13.0 - Unauthenticated reCAPTCHA v3 Bypass via Missing Score Validation",
 "description": "The SureForms plugin for WordPress is vulnerable to a CAPTCHA protection bypass via the reCAPTCHA v3 check on form submissions in all versions up to, and including, 2.13.0. Server-side verification accepted any siteverify response with success set to true and never compared the v3 score to a threshold. This makes it possible for unauthenticated attackers, such as automated bots that obtain a low-scoring v3 token, to bypass the spam protection the site owner enabled on a form and submit entries at will.",
