DescriptionCVE.org

The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.6.2 via the process. This makes it possible for unauthenticated attackers to extract arbitrary WordPress post meta values — including license keys, API tokens, SMTP credentials, and Stripe or AWS secrets stored on any post type — via form submission notification emails or stored entries. The submission nonce is publicly rendered in every embedded form and can additionally be minted anonymously via the nopriv everest_forms_get_form_update_nonce action, meaning no account or prior authentication of any kind is required to complete the exploit.
