CVE-2025-11517Event Tickets and Registration <= 5.26.5 - Unauthenticated Ticket Payment Bypass
High 7.5
In plain English
A high-severity authorization bypass via user-controlled key in Event Tickets and Registration from stellarwp. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 35% of all known vulnerabilities).
Official description
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.
