The Login/Signup Popup plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on several functions in versions up to, and including, 1.4. This makes it possible for authenticated attackers to inject arbitrary web scripts into the plugin settings that execute if they can successfully trick a user into performing an action such as clicking on a link.

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).

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

The OTP Login Woocommerce & Gravity Forms plugin for WordPress is vulnerable to authentication bypass. This is due to the fact that when generating OTP codes for users to use in order to login via phone number, the plugin returns these codes in an AJAX response. This makes it possible for unauthenticated attackers to obtain login codes for administrators. This does require an attacker have access to the phone number configured for an account, which can be obtained via social engineering or reconnaissance.

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

Multiple plugins for WordPress utilizing the XootiX Framework are vulnerable to unauthorized modification of data due to a missing capability check on the 'import_settings' function in various versions. 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.

The Login/Signup Popup ( Inline Form + Woocommerce ) plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the ‘export_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 read arbitrary options on affected sites.

The Login/Signup Popup ( Inline Form + Woocommerce ) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's xoo_el_action shortcode in all versions up to, and including, 2.8.5 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.
