## Affected

- Unknown Event Tickets Manager for WooCommerce: from 1.5.4, fixed in 1.6.0

## Description

The Event Tickets Manager for WooCommerce WordPress plugin before 1.6.0 does not validate the ticket-type price sent to one of its unauthenticated AJAX actions when the referenced product has no ticket types configured, and stores the submitted price site-wide, where it is applied to the next event ticket added to any cart, allowing unauthenticated visitors to buy event tickets at an arbitrary price, including for free. This is due to an incomplete fix of CVE-2026-34898.
