Metform Elementor Contact Form Builder < 3.3.1 - Multiple Contributor+ Stored XSS via Shortcode

Description

The plugin does not properly sanitize and escape user input when processed by many of its shortcodes, which could enable users with contributor privileges to conduct Stored Cross-Site Scripting attacks on the site. Affected shortcodes include mf, mf_first_name, mf_last_name, and mf_thankyou.
