Description
The Fluent Booking plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.1.1. This is due to missing per-booking access verification on the attendee export endpoint, which only checked for a broad Calendar Manager role rather than validating the requesting user's access to the specific booking group. This makes it possible for authenticated attackers, with calendar manager-level access and above, to export attendee booking data belonging to calendar groups they do not have permission to manage by supplying an arbitrary group_id parameter.
