ESLint rules for Node Security
ESLint rules for Node Security
This project will help identify potential security hotspots, but finds a lot of false positives which need triage by a human.
npm install --save-dev eslint-plugin-securityor
yarn add --dev eslint-plugin-securityAdd the following to your eslint.config.js file:
const pluginSecurity = require('eslint-plugin-security');
module.exports = [pluginSecurity.configs.recommended];Add the following to your .eslintrc file:
module.exports = {
extends: ['plugin:security/recommended-legacy'],
};npm run-script cont-intnpm test⚠️ Configurations set to warn in.
✅ Set in the recommended configuration.
| Name | Description | ⚠️ |
|---|---|---|
| detect-bidi-characters | Detects trojan source attacks that employ unicode bidi attacks to inject malicious code. | ✅ |
| detect-buffer-noassert | Detects calls to "buffer" with "noAssert" flag set. | ✅ |
| detect-child-process | Detects instances of "child_process" & non-literal "exec()" calls. | ✅ |
| detect-disable-mustache-escape | Detects "object.escapeMarkup = false", which can be used with some template engines to disable escaping of HTML entities. | ✅ |
| detect-eval-with-expression | Detects "eval(variable)" which can allow an attacker to run arbitrary code inside your process. | ✅ |
| detect-invisible-characters | Detects invisible characters that have no visible glyph and can be used to hide malicious code. | ✅ |
| detect-new-buffer | Detects instances of new Buffer(argument) where argument is any non-literal value. | ✅ |
| detect-no-csrf-before-method-override | Detects Express "csrf" middleware setup before "method-override" middleware. | ✅ |
| detect-non-literal-fs-filename | Detects variable in filename argument of "fs" calls, which might allow an attacker to access anything on your system. | ✅ |
| detect-non-literal-regexp | Detects "RegExp(variable)", which might allow an attacker to DOS your server with a long-running regular expression. | ✅ |
| detect-non-literal-require | Detects "require(variable)", which might allow an attacker to load and run arbitrary code, or access arbitrary files on disk. | ✅ |
| detect-object-injection | Detects "variable[key]" as a left- or right-hand assignment operand. | ✅ |
| detect-possible-timing-attacks | Detects insecure comparisons (==, !=, !== and ===), which check input sequentially. |
✅ |
| detect-pseudoRandomBytes | Detects if "pseudoRandomBytes()" is in use, which might not give you the randomness you need and expect. | ✅ |
| detect-unsafe-regex | Detects potentially unsafe regular expressions, which may take a very long time to run, blocking the event loop. | ✅ |
