Title
Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin <= 1.6.7.7 - Authenticated (Subscriber+) SQL Injection
Summary
The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to SQL Injection via the keys parameter in all versions up to, and including, 1.6.7.7 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 subscriber access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
