eslint-plugin-node-security

⭐ If this plugin caught a real bug for you, star the repo — it's the signal that keeps these rules maintained.

Description

This plugin provides Security rules for Node.js core modules (fs, child_process, crypto, etc).

• Why — a linter nobody reads protects nothing. We would rather miss a finding than spend your attention on one that was never real.
• How — evidence, not names. A rule fires on what the code does, resolved through the AST and ESLint's own scope analysis.
• What — every finding carries its fix, in prose for a human and as structured JSON for an agent. Security rules add a CWE mapping and, where assigned, a CVSS score.

That trade costs recall, and we measure it: methodology · results · a false positive is a bug.

Getting Started

• To check out the guide, visit eslint.interlace.tools. 📚

npm install eslint-plugin-node-security --save-dev

⚙️ Configuration Presets

💡 What You Get

• 31 security rules covering Node.js core module vulnerabilities
• Command Injection Detection for child_process.exec, spawn, and execFile
• Path Traversal Prevention for fs module operations
• TOCTOU Race Condition Detection for file system operations
• Cryptographic Security for weak algorithms and key management
• LLM-optimized messages with CWE references and fix guidance

📦 Compatibility

See the ESLint Version Support Policy — current ecosystem share data, the 20% gate, and the forward-looking exception that covers v10.
