Abandoned Cart Lite for WooCommerce < 5.16.2 - Missing Authorization via multiple AJAX functions

Description

The Abandoned Cart Lite for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to missing capability checks on multiple AJAX functions in versions up to, and including, 5.16.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to dismiss admin notifications, toggle templates, view abandoned cart details, and preview emails.
