HUSKY – Products Filter Professional for WooCommerce <= 1.3.7.3 - Authenticated (Subscriber+) Insecure Direct Object Reference via 'woof_add_subscr'

The HUSKY – Products Filter Professional for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.3.7.3 via the "woof_add_subscr" function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber level access and above, to create product messenger subscriptions on behalf of arbitrary users, including administrators.
