Integration for WooCommerce and QuickBooks <= 1.2.3 - Open Redirect via setup_plugin

The Integration for WooCommerce and QuickBooks plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 1.2.3. This is due to insufficient validation on the redirect url supplied by the user in the setup_plugin function. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
