WholesaleX < 1.3.2 - Authenticated(Subscriber+) Missing Authorization via multiple AJAX actions

Description

The WholesaleX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wc_install_callback AJAX function in versions up to, and including, 1.3.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to install woocommerce.
