## Description

The Events Made Easy plugin for WordPress is vulnerable to authorization bypass via the frontend booking form handler in all versions up to, and including, 3.2.22, due to the eme_is_admin_request() function deciding whether a request comes from the admin area based on the client-controlled referer (the Referer header or the _wp_http_referer parameter). This makes it possible for authenticated attackers, with Subscriber-level access and above, to have their frontend booking requests treated as backend bookings. They can then skip the event's RSVP password, approval and frontend validation checks, overbook when admin overbooking is enabled, and supply an arbitrary WordPress user ID for the booker.
