What the vulnerability does
The Event Tickets and Registration plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 5.26.5. This is due to the /wp-json/tribe/tickets/v1/commerce/free/order endpoint not verifying that a ticket type should be free allowing the user to bypass the payment. This makes it possible for unauthenticated attackers to obtain access to paid tickets, without paying for them, causing a loss of revenue for the target.
Explanation of Vulnerability in Simple Terms
Event Tickets and Registration versions up to 5.26.5 contain an authorization bypass that allows unauthenticated attackers to modify event data over the network. The vulnerability stems from insufficient access controls on sensitive operations. No user interaction is required. Site administrators should update to a version newer than 5.26.5 immediately.
What an attacker can do
Modify event ticket data and registration information without authentication.
Potential impact on your site
Attackers can alter event details, pricing, or registrations without logging in, disrupting event management.
Conditions required to exploit
Network access only; no authentication or user interaction required.
