WP Hotel Booking < 2.0.9.3 - Improper Authorization on Multiple REST API Routes

Description

The WP Hotel Booking plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to an improper capability check on the 'pricing_plans', 'block_date', 'manager_bookings', and 'update_field_room' functions for the 'pricing-plans', 'block-date', 'manager-bookings', and 'update-field' REST routes, respectively, in versions up to, and including, 2.0.9.2. This makes it possible for unauthenticated attackers to expose sensitive information about bookings or modify them.
