ilGhera Support System for WooCommerce <= 1.2.6 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Ticket Deletion

The ilGhera Support System for WooCommerce plugin for WordPress is vulnerable to unauthorized modification and loss of data due to a missing capability check on the 'delete_single_ticket_callback' and 'change_ticket_status_callback' functions in all versions up to, and including, 1.2.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary support tickets and modify their status.
