To prevent MongoDB injection, you must enforce primitive input validation and use safe query construction so user input cannot influence query operators like $gt, $ne, or $regex. This blocks operator injection and data leakage.

NoSQL injection occurs when user input manipulates query operators or query structure in databases like MongoDB, potentially bypassing authentication and leaking data by exploiting operators like $ne or executing JavaScript in the database engine.

Yes, the NoSQL injection check applies to MongoDB, Elasticsearch, and similar NoSQL stores where user input can influence query operators or query structure across common workloads.

You validate and sanitize request parameters by enforcing primitive input validation and applying query sanitization before building MongoDB queries, ensuring user input cannot shape query filters or inject dangerous operators.

The best way to detect vulnerable patterns is to run an analysis that identifies where user input shapes query filters or operators, recommending safe query construction and input validation to prevent operator injection.

You should worry about JavaScript execution in your NoSQL database engine when user input can influence query structure, as attackers can exploit it to bypass authentication and leak data through NoSQL injection flaws.
