eslint-plugin-secure-coding

⭐ 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 General secure coding practices and OWASP compliance for JavaScript/TypeScript.

• 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-secure-coding --save-dev

Add to your eslint.config.mjs — one line activates 16 security rules:

import securePlugin from 'eslint-plugin-secure-coding';

export default [
  // Balanced: catches critical issues as errors, lower-confidence rules as warnings
  ...securePlugin.configs.recommended,

  // Zero-tolerance: same 16 rules, all promoted to error (good for CI gates)
  // ...securePlugin.configs['recommended-strict'],
];

Or if you use a legacy .eslintrc.json:

{
  "extends": ["plugin:secure-coding/recommended"]
}

Using recommended already? Extend your coverage with domain-specific plugins: eslint-plugin-node-security (crypto, eval, buffer) · eslint-plugin-jwt-security (JWT auth) · eslint-plugin-express-security (Express middleware)

Benchmarks vs competitors (CWE-798 ground truth)

no-hardcoded-credentials is part of the ILB-Flagship benchmark suite. On the labeled CWE-798 fixture set (Juliet-style: 2 vulnerable + 2 safe files, ground-truthed):

The competitor's entropy-only detection catches the high-entropy API-key shape but misses the 15-character literal password assigned to password:. Our context-gated detection (structural patterns + credential-named-variable check + context-positive path) catches both for the right reasons.

On real OSS (vercel/ai), the competitor reports ~380 more findings than us. Those 380 are not catches we missed — they're entropy false-positives on TypeScript type literals ('experimental_onLanguageModelCallStart'), error class names ('AI_ToolCallNotFoundForApprovalError'), and documentation URLs. Sampling confirmed zero are actual credentials. The corpus number is the right one to weigh; the OSS finding-count is a noise metric.
