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.

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.
