SureForms – Contact Form, Payment Form & Other Custom Form Builder

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 Contact Form Builder – Multi-step Forms, Conversational Forms and more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.9.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions up to, and including, 1.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_entry_files() function in all versions up to, and including, 1.7.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.7.3 via the use of file_exists() in the delete_entry_files() function without restriction on the path provided. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.4.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
