Fluent Booking – The Ultimate Appointments Scheduling, Events Booking, Events Calendar Solution <= 1.9.11 - Authenticated (Subscriber+) Missing Authorization to Calendar Import and Management

The Fluent Booking plugin for WordPress is vulnerable to unauthorized calendar import and management due to a missing capability check on the "importCalendar" function in all versions up to, and including, 1.9.11. This makes it possible for authenticated attackers, with subscriber level access and above, to import arbitrary calendars and manage them.
