The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.3.0 via file upload due to missing validation on a user controlled key.

If an admin enables tickets for guests, this can be exploited by unauthenticated attackers.
