Event Tickets <= 5.18.1 - Insecure Direct Object Reference to Sensitive Information Exposure
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The Event Tickets and Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.18.1 via the tc-order-id parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view order details of orders they did not place, which includes ticket prices, user emails and order date.
