WP Simple Booking Calendar <= 2.0.6 (before 07/12/2021) - Authenticated SQL Injection

The plugin did not escape, validate or sanitise the orderby parameter in its Search Calendars action, before using it in a SQL statement, leading to an authenticated SQL injection issue

Note (WPScanTeam): The issue was fixed without bumping the version, so there are two 2.0.6 versions out there, one vulnerable, the other with the fix.
