The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 4.16.7 due to insufficient input sanitization on the type parameter in the form preview functionality. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes via the pp_preview_form endpoint.
