The Pie Register – User Registration, Profiles & Content Restriction plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the pie_main() function in all versions up to, and including, 3.8.4.8. This makes it possible for unauthenticated attackers to change registration form status.

The Pie Forms for WP plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6 via the format_classic function. This is due to insufficient file type validation where the validate_classic method validates file extensions and sets error messages but does not prevent the file upload process from continuing. This makes it possible for unauthenticated attackers to upload files with dangerous extensions such as PHP, which makes remote code execution possible. In order to exploit this vulnerability, the attacker needs to guess the directory in which the file is placed (which is a somewhat predictable hash). In addition to that, the file name is generated using a secure hash method, limiting the exploitability of this vulnerability.

The Registration Forms – User Registration Forms, Invitation-Based Registrations, Front-end User Profile, Login Form & Content Restriction plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.8.4 through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information about users contained in the exposed log files.

The Drag & Drop Builder, Human Face Detector, Pre-built Templates, Spam Protection, User Email Notifications & more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'page' parameter in all versions up to, and including, 1.4.19 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 Web and WooCommerce Addons for WPBakery Builder plugin for WordPress is vulnerable to unauthorized plugin settings modification due to a missing capability check on several plugin functions in all versions up to, and including, 1.4.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change some of the plugin settings.

The Registration Forms – User Registration Forms, Invitation-Based Registrations, Front-end User Profile, Login Form & Content Restriction plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the pieregister_install_addon function in all versions up to, and including, 3.8.3.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to install arbitrary plugins. As a result attackers might achieve code execution on the targeted server
