Booking Manager < 2.1.6 - Authenticated(Contributor+) SQL Injection via Shortcode

Description The Booking Manager plugin for WordPress is vulnerable to SQL Injection via the plugin’s shortcode attributes in all versions up to 2.1.6 (exclusive) due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
