# Howto Catch Risky JavaScript Bugs with eslint-plugin-security

**[JS Dev Space](https://daily.dev/sources/jsdev-space)** · 8 min read · 0 upvotes · 0 comments

## Summary

eslint-plugin-security adds a security-focused linting layer to JavaScript and Node.js projects, catching dangerous patterns that standard ESLint misses. The guide covers installation, ESLint v9 Flat Config and legacy .eslintrc setup, and six key vulnerability categories: dynamic eval(), non-literal require(), unsafe child process execution (command injection), object injection and prototype pollution, ReDoS-prone regular expressions, and timing attack risks. It also addresses handling false positives, TypeScript integration, CI enforcement via GitHub Actions, and how the plugin compares to npm audit and full SAST tools. Recommended for Node.js APIs, Express/NestJS/Next.js backends, and CLI utilities.
