Delhivery Logistics Courier <= 1.0.107 is vulnerable to Subscriber+ SQL Injection vulnerability

The Delhivery Logistics Courier plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 1.0.107 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-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
