Summary
The FooSales plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to and including 1.43.0. The plugin does not properly validate a user's identity before updating their details, allowing authenticated attackers with Cashier-level access or above to change arbitrary users' email addresses, including administrators, and then reset passwords and gain access.

Original NVD description (English source)
The FooSales – Point of Sale (POS) for WooCommerce plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.43.0. This is due to the plugin not properly validating a user's identity prior to updating their details like email. This makes it possible for authenticated attackers, with FooSales Cashier-level access and above, to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.
