Is there any "paramaterized" format that allows you to specify the query in a format other than simply passing in query objects. You can help guard against SQL injections attacks by: Using a sanitization library like Mongoose. This article shows how a Node.js application based on Express and using MongoDB (with Mongoose ORM) can be vulnerable to NoSQL injections. Mongo stores data as single and usually unconnected Javascript objects. NoSQL injection also allows privilege escalation and account hijacking. Suppose, your application is accepting JSON username and password, so it can be . In this post, we're going to specifically look at protecting our MongoDB from injection attacks.
