fiznool/express-mongo-sanitize

This project provides Express 4.x middleware to sanitize user-supplied data and prevent MongoDB operator injection attacks. It automatically scans `req.body`, `req.query`, `req.headers`, and `req.params` for keys containing `$` or `.`, either removing them or replacing prohibited characters based on configuration options. The tool is essential for developers building Express applications that interact with MongoDB databases and need to protect against malicious input.
