NextMove Lite – Thank You Page for WooCommerce < 2.20.0 - Missing Authorization to Authenticated (Subscriber+) Deactivation Reason Submission

Description

The NextMove Lite – Thank You Page for WooCommerce plugin for WordPress is vulnerable to unauthorized submission of data due to a missing capability check on the _submit_uninstall_reason_action() function in all versions up to, and including, 2.19.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to submit a deactivation reason on behalf of a site.
