ELEX WordPress HelpDesk & Customer Ticketing System <= 3.3.0 - Missing Authorization to Authenitcated (Subscriber+) to Scheduled Trigger Deletion

The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_eh_crm_settings_empty_scheduled_actions' AJAX Action in all versions up to, and including, 3.3.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the scheduled triggers option.
