Header Injection Protection + +When signing tokens with custom headers, dangerous keys are filtered out: + +```javascript +// This attack is prevented +const maliciousOptions = { + header: { + "__proto__": { + "isAdmin": true + } + } +}; + +const token = await jwt.sign(payload, secret, maliciousOptions); +// The __proto__ key is filtered out, preventing pollution +``` + +#### 2. JSON Parsing Protection + +When decoding tokens, the library uses a safe JSON parser that filters dangerous keys: + +```javascript +// Even if a JWT contains __proto__ in its payload +// it won't pollute the prototype when decoded +const decoded = jwt.decode(maliciousToken); +// Dangerous keys like __proto__, constructor, and prototype are removed +``` + +### Protected Keys + +The following keys are filtered to prevent pollution: +- `__proto__` +- `constructor` +- `prototype` + +## Denial of Service (DoS) Protection + +As of v10.0.0, the library includes built-in protection against DoS attacks through configurable size and complexity limits. + +### Attack Vectors Prevented + +#### 1. Large Token Attack +Attackers can create massive JWTs to exhaust server memory: +```javascript +// This attack is now prevented by default +const hugePayload = { + data: 'A'.repeat(100 * 1024 * 1024) // 100MB +}; +const token = await jwt.sign(hugePayload, secret); +// Throws: JWT exceeds maximum allowed size +``` + +#### 2. Deep Nesting Attack +Deeply nested objects cause exponential parsing time: +```javascript +// This attack is now prevented +let payload = { a: 1 }; +for (let i = 0; i < 1000; i++) { + payload = { nested: payload }; +} +const token = await jwt.sign(payload, secret); +// Throws: JWT payload exceeds maximum allowed depth +``` + +#### 3. Claim Explosion Attack +Thousands of claims can exhaust memory: +```javascript +// This attack is now prevented +const payload = {}; +for (let i = 0; i < 50000; i++) { + payload[`claim${i}`] = `value${i}`; +} +const token = await jwt.sign(payload, secret); +// Throws: JWT payload exceeds maximum allowed claim count +``` + +### Configurable Limits + +All limits can be configured per operation: + +```javascript +// Custom limits for sign +const token = await jwt.sign(payload, secret, { + maxTokenSize: 500 * 1024, // 500KB total token size + maxPayloadSize: 200 * 1024, // 200KB payload size + maxPayloadDepth: 100, // 100 levels deep + maxClaimCount: 2000 // 2000 total claims +}); + +// Custom limits for verify +const decoded = await jwt.verify(token, secret, { + maxTokenSize: 500 * 1024, + maxPayloadSize: 200 * 1024, + maxPayloadDepth: 100, + maxClaimCount: 2000 +}); + +// Custom limits for decode +const payload = jwt.decode(token, { + maxTokenSize: 500 * 1024, + maxPayloadSize: 200 * 1024, + maxPayloadDepth: 100, + maxClaimCount: 2000 +}); +``` + +### Default Limits + +The library uses sensible defaults that work for 99.9% of legitimate use cases: + +| Limit | Default Value | Description | +|-------|---------------|-------------| +| `maxTokenSize` | 250KB | Maximum size of the entire JWT string | +| `maxPayloadSize` | 100KB | Maximum size of the decoded payload | +| `maxPayloadDepth` | 50 | Maximum nesting depth of objects | +| `maxClaimCount` | 1000 | Maximum total number of claims | + +### Disabling DoS Protection + +For backward compatibility or special use cases, DoS protection can be disabled: + +```javascript +// ⚠️ WARNING: Only disable for trusted inputs +const token = await jwt.sign(largePayload, secret, { + disableDoSProtection: true +}); + +const decoded = await jwt.verify(token, secret, { + disableDoSProtection: true +}); +``` + +### Best Practices for DoS Protection + +1. **Keep Default Limits**: The defaults are generous for legitimate use +2. **Monitor Token Sizes**: Log warnings when tokens approach limits +3. **Validate Before Signing**: Check payload size before creating tokens +4. **Set Appropriate Limits**: Adjust based on your specific use case +5. **Never Disable for Public APIs**: Always enforce limits on untrusted input + +## Best Practices + +### 1. Always Verify Tokens + +Never trust a JWT without verification: + +```javascript +// ❌ Bad - No verification +const decoded = jwt.decode(token); + +// ✅ Good - Proper verification +const decoded = await jwt.verify(token, secret); +``` + +### 2. Use Strong Keys + +- **HMAC**: Use keys at least 256 bits (32 bytes) long +- **RSA**: Use keys with at least 2048-bit modulus +- **ECDSA**: Use appropriate curves (P-256, P-384, P-521) + +```javascript +// ❌ Bad - Weak secret +const token = await jwt.sign(payload, 'secret123'); + +// ✅ Good - Strong secret +const token = await jwt.sign(payload, crypto.randomBytes(32)); +``` + +### 3. Always Specify Algorithms + +When verifying, always specify allowed algorithms: + +```javascript +// ❌ Bad - No algorithm restriction +const decoded = await jwt.verify(token, publicKey); + +// ✅ Good - Explicit algorithm +const decoded = await jwt.verify(token, publicKey, { + algorithms: ['RS256'] +}); +``` + +### 4. Set Token Expiration + +Always set token expiration to limit exposure: + +```javascript +const token = await jwt.sign(payload, secret, { + expiresIn: '1h' // Token expires in 1 hour +}); +``` + +### 5. Validate All Claims + +Verify audience, issuer, and other claims: + +```javascript +const decoded = await jwt.verify(token, secret, { + audience: 'your-app.com', + issuer: 'auth.your-app.com', + clockTolerance: 10 // 10 seconds clock skew tolerance +}); +``` + +## Security Warnings + +### 1. The 'none' Algorithm + +The `none` algorithm provides **NO security**. It must be explicitly enabled: + +```javascript +// ⚠️ DANGEROUS - Only use for testing +const unsignedToken = await jwt.sign(payload, '', { + algorithm: 'none', + allowInsecureNoneAlgorithm: true +}); +``` + +### 2. Algorithm Confusion + +Never allow tokens to specify their own algorithm without validation: + +```javascript +// ❌ Bad - Algorithm from token +const header = jwt.decode(token, { complete: true }).header; +const decoded = await jwt.verify(token, key, { + algorithms: [header.alg] +}); + +// ✅ Good - Predefined algorithms +const decoded = await jwt.verify(token, key, { + algorithms: ['RS256', 'RS384'] +}); +``` + +### 3. Key Storage + +- Never commit keys to version control +- Use environment variables or secure key management systems +- Rotate keys regularly +- Use different keys for different environments + +### 4. Header Injection + +Be cautious with dynamic header values: + +```javascript +// ✅ Safe - Prototype pollution protection is automatic +const token = await jwt.sign(payload, secret, { + header: userProvidedHeader // Safe due to filtering +}); +``` + +### 5.
