The BookingPress Appointment Booking Pro plugin for WordPress is vulnerable to SQL Injection via the 'store_service_date' parameter of the bpa_assign_staffmember_to_slots() function in versions up to and including 5.7.1. This is due to the explicit use of stripslashes_deep() on user-supplied POST data before it is interpolated verbatim into a SQL LIKE clause without use of $wpdb->prepare() or any parameterization. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
