The SureForms – Contact Form, Payment Form & Other Custom Form Builder plugin for WordPress is vulnerable to Payment Amount Bypass in all versions up to, and including, 2.5.2. This is due to the create_payment_intent() function performing a payment validation solely based on the value of a user-controlled parameter. This makes it possible for unauthenticated attackers to bypass configured form payment-amount validation and create underpriced payment/subscription intents by setting form_id to 0.

The SureForms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form field parameters in all versions up to, and including, 2.2.0 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 SureForms plugin for WordPress is vulnerable to Cross-Site Request Forgery Bypass in all versions up to, and including, 1.13.1. This is due to the plugin distributing generic WordPress REST API nonces (wp_rest) to unauthenticated users via the 'wp_ajax_nopriv_rest-nonce' action. While the plugin legitimately needs to support unauthenticated form submissions, it incorrectly uses generic REST nonces instead of form-specific nonces. This makes it possible for unauthenticated attackers to bypass CSRF protection on REST API endpoints that rely solely on nonce verification without additional authentication checks, allowing them to trigger unauthorized actions such as the plugin's own post-submission hooks and potentially other plugins' REST endpoints.

The SureForms plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.13.1 via the '_srfm_email_notification' post meta registration. This is due to setting the 'auth_callback' parameter to '__return_true', which allows unauthenticated access to the metadata. This makes it possible for unauthenticated attackers to extract sensitive data including email notification configurations, which frequently contain vendor-provided CRM/help desk dropbox addresses, CC/BCC recipients, and notification templates that can be abused to inject malicious data into downstream systems.

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to Sensitive Information Disclosure in all versions up to, and including, 1.12.1. This is due to improper access control implementation on the '/wp-json/sureforms/v1/srfm-global-settings' REST API endpoint. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve sensitive information including API keys for Google reCAPTCHA, Cloudflare Turnstile, hCaptcha, admin email addresses, and security-related form settings.

The SureForms – Drag and Drop Contact Form Builder – Multi-step Forms, Conversational Forms and more plugin for WordPress is vulnerable to unauthorized creation of forms due to a missing capability check on the register_post_types() function in all versions up to, and including, 1.12.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to create forms when the user interface specifically prohibits it.

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.2.2 via the handle_export_form() function due to a missing capability check. This makes it possible for unauthenticated attackers to export data from password protected, private, or draft posts that they should not have access to.
