The WooCommerce Customers Manager plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the ajaxassignnewroles() function in all versions up to, and including, 31.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator.

The WooCommerce Customers Manager WordPress plugin before 30.2 does not have authorisation and CSRF in various AJAX actions, allowing any authenticated users, such as subscriber, to call them and update/delete/create customer metadata, also leading to Stored Cross-Site Scripting due to the lack of escaping of said metadata values.

The WooCommerce Customers Manager WordPress plugin before 30.1 does not have CSRF checks in some places, which could allow attackers to make logged in admin users delete users via CSRF attacks

The WooCommerce Customers Manager WordPress plugin before 30.1 does not have CSRF checks in some bulk actions, which could allow attackers to make logged in admins perform unwanted actions, such as deleting customers via CSRF attacks

The WooCommerce Customers Manager WordPress plugin before 29.8 does not sanitise and escape various parameters before outputting them back in pages and attributes, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

The WooCommerce Customers Manager WordPress plugin before 29.8 does not have authorisation and CSRF in an AJAX action, allowing any authenticated users, such as subscriber, to call it and retrieve the list of customer email addresses along with their id, first name and last name

The WooCommerce Customers Manager WordPress plugin before 29.7 does not properly sanitise and escape a parameter before using it in a SQL statement, leading to an SQL injection exploitable by Subscriber+ role.
