The WooCommerce Customers Manager plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the ajax_assign_new_roles() 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 30.1 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 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.
