Description
The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.2.9 via the 'eh_crm_ticket_single_view_client' due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of all support tickets.
