{"id":43942,"library":"sql-sanitizer","title":"sql-sanitizer","description":"An Express.js middleware that detects and blocks SQL injection attacks by inspecting query strings, route parameters, and request bodies for common SQL injection patterns. Version 1.0.0 is the initial release with no further updates, limited to basic blacklist-based detection, and provides no configuration options, making it unsuitable for production without additional validation. Compared to more robust alternatives like knex or parameterized queries, this package offers minimal protection and is considered a last-resort or learning tool.","status":"active","version":"1.0.0","language":"javascript","source_language":"en","source_url":"https://github.com/Tanmoy-Barua/sql-sanitizer","tags":["javascript","SQL","INJECTION","sql","injection","express-sqlinjection"],"install":[{"cmd":"npm install sql-sanitizer","lang":"bash","label":"npm"},{"cmd":"yarn add sql-sanitizer","lang":"bash","label":"yarn"},{"cmd":"pnpm add sql-sanitizer","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Middleware designed specifically for Express.js framework","package":"express","optional":true}],"imports":[{"note":"Package is ESM-only since v1?
