The Login/Signup Popup ( Inline Form + Woocommerce ) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'import_settings' function in versions 2.7.1 to 2.7.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change arbitrary options on affected sites. This can be used to enable new user registration and set the default role for new users to Administrator.

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in XootiX Side Cart Woocommerce (Ajax) plugin <= 2.2 versions.

Cross-Site Request Forgery (CSRF) vulnerability in XootiX Side Cart Woocommerce (Ajax) < 2.1 versions.

The Login/Signup Popup, Waitlist Woocommerce ( Back in stock notifier ), and Side Cart Woocommerce (Ajax) WordPress plugins by XootiX are vulnerable to Cross-Site Request Forgery via the save_settings function found in the ~/includes/xoo-framework/admin/class-xoo-admin-settings.php file which makes it possible for attackers to update arbitrary options on a site that can be used to create an administrative user account and grant full privileged access to a compromised site. This affects versions <= 2.2 in Login/Signup Popup, versions <= 2.5.1 in Waitlist Woocommerce ( Back in stock notifier ), and versions <= 2.0 in Side Cart Woocommerce (Ajax).
