Is MetForm safe? Known vulnerabilities and latest version

Missing Authorization vulnerability in Wpmet Metform metform allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Metform: from n/a through 4.3.2.

The MetForm WordPress plugin before 4.3.1 does not sanitize or escape submitted form-field values before inserting them into the HTML body of its email notifications, allowing unauthenticated attackers to inject arbitrary markup into the administrator and submitter notification emails the site sends.

The MetForm WordPress plugin before 4.3.1 does not properly restrict access to a debug file it writes to the web root on every form submission when its HubSpot Forms integration is enabled, allowing unauthenticated attackers to read upstream API response data, including correlation identifiers and cookies.

The MetForm WordPress plugin before 4.3.1 does not properly restrict access to form submission data, allowing unauthenticated attackers to view submitter information through the REST API.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Wpmet Metform metform allows Stored XSS.This issue affects Metform: from n/a through 4.3.0.

The MetForm WordPress plugin before 4.1.9 does not properly neutralize newline characters in user-submitted values that are placed into notification email headers, allowing unauthenticated attackers to inject additional email headers, such as Bcc, into the emails the site sends when a submitted field value is configured to populate a header.

The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'mf_form_id' Widget Setting in all versions up to, and including, 4.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload bypasses Elementor's save-time wp_kses_post filter because it contains no HTML tags, and MetForm's own str_replace transformation of script tags into JavaScript template literal expressions provides an additional delivery path.

The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.1.0. This is due to the use of a forgeable cookie value derived only from the entry ID and current user ID without a server-side secret. This makes it possible for unauthenticated attackers to access form submission entry data via MetForm shortcodes for entries created within the transient TTL (default is 15 minutes).

The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `mf-template` DOM Element in all versions up to, and including, 4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Server-Side Request Forgery (SSRF) vulnerability in Roxnor Metform metform allows Server Side Request Forgery.This issue affects Metform: from n/a through <= 3.9.2.

Missing Authorization vulnerability in Roxnor Metform metform allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Metform: from n/a through <= 3.4.0.

The Metform Elementor Contact Form Builder for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in versions up to, and including, 3.2.4. This allows unauthenticated visitors to perform a "double extension" attack and upload files containing a malicious extension but ending with a benign extension, which may make remote code execution possible in some configurations.

The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 3.8.8 via the 'handle_file' function. This can allow unauthenticated attackers to extract sensitive data, such as Personally Identifiable Information, from files uploaded by users.

Missing Authorization vulnerability in Roxnor Metform metform.This issue affects Metform: from n/a through <= 3.8.3.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's widgets in all versions up to, and including, 3.8.5 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 3.8.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.1. This is due to missing or incorrect nonce validation on the contents function. This makes it possible for unauthenticated attackers to update the options "mf_hubsopt_token", "mf_hubsopt_refresh_token", "mf_hubsopt_token_type", and "mf_hubsopt_expires_in" via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This would allow an attacker to connect their own Hubspot account to a victim site's metform to obtain leads and contacts.

The Metform Elementor Contact Form Builder for WordPress is vulnerable to Information Disclosure via the 'mf_first_name' shortcode in versions up to, and including, 3.3.1. This allows authenticated attackers, with subscriber-level capabilities or above to obtain sensitive information about arbitrary form submissions, including the submitter's first name.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.3.2. This is due to missing or incorrect nonce validation on the permalink_setup function. This makes it possible for unauthenticated attackers to change the permalink structure via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. While nonce verification is implemented, verification only takes place when a nonce is provided.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to unauthorized permalink structure update due to a missing capability check on the permalink_setup function in versions up to, and including, 3.3.0. This makes it possible for unauthenticated attackers to change the permalink structure.

The Metform Elementor Contact Form Builder for WordPress is vulnerable to Cross-Site Scripting by using the 'fname' attribute of the 'mf_thankyou' shortcode to echo unescaped form submissions in versions up to, and including, 3.3.0. This allows authenticated attackers, with contributor-level permissions or above, to inject arbitrary web scripts in pages that will execute when the victim visits a a page containing the shortcode when the submission id is present in the query string. Note that getting the JavaScript to execute requires user interaction as the victim must visit a crafted link with the form entry id, but the script itself is stored in the site database. Additionally this requires successful payment, increasing the complexity.

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to CSV injection in versions up to, and including, 3.3.0. This allows unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

This allows authenticated attackers, with contributor-level permissions or above, to inject arbitrary web scripts in pages that will execute when the victim visits a specific link. Note that getting the JavaScript to execute still requires user interaction as the victim must visit a crafted link with the form entry id, but the script itself is stored in the site database.
