Before we do, lets take a quick look at why NoSQL databases are no less vulnerable to Injection attacks than RDMBS database and some would argue, more susceptible. A NoSQL injection attack is similar to SQL injection vulnerabilities in that they take advantage of sanitized user input while constructing database queries. Is there any "paramaterized" format that allows you to specify the query in a format other than simply passing in query objects. An injection is a security vulnerability that lets attackers take control of database queries through the unsafe use of user input. NoSQL injection is a security weakness in a web application that uses a NoSQL database.
