Course Booking System <= 6.0.5 - Unauthenticated SQL Injection

# Description

The Course Booking System plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 6.0.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
