## Description

The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in versions 4.1.24 up to, and including, 4.1.25 because the event JSON-LD structured data uses the event's virtual meeting join link as its location URL. When schema mark-up is enabled, this makes it possible for unauthenticated attackers to read Zoom, Google Meet or other join links for online and hybrid events from the public event page source without buying a ticket.
