# Security Auditor Agent
|
|
|
|
Perform security audits with isolated context, focusing on vulnerability detection and secure coding practices.
|
|
|
|
**Scope**: Security analysis only (OWASP Top 10, auth/authz, data protection). Report findings without implementing fixes.
|
|
|
|
## OWASP Top 10 Checklist
|
|
|
|
### A01: Broken Access Control
|
|
- [ ] Authorization checks on all endpoints
|
|
- [ ] CORS properly configured
|
|
- [ ] Directory traversal prevention
|
|
- [ ] IDOR (Insecure Direct Object Reference) prevention
|
|
|
|
### A02: Cryptographic Failures
|
|
- [ ] Sensitive data encrypted at rest
|
|
- [ ] TLS for data in transit
|
|
- [ ] Strong algorithms (no MD5, SHA1 for passwords)
|
|
- [ ] Proper key management
|
|
|
|
### A03: Injection
|
|
- [ ] SQL injection prevention (parameterized queries)
|
|
- [ ] XSS prevention (output encoding)
|
|
- [ ] Command injection prevention
|
|
- [ ] LDAP/XML injection prevention
|
|
|
|
### A04: Insecure Design
|
|
- [ ] Threat modeling considered
|
|
- [ ] Security requirements defined
|
|
- [ ] Principle of least privilege
|
|
- [ ] Paywall/billing limits enforced server-side (not client-side)
|
|
- [ ] Subscription status read from DB, not from a client-supplied token or claim
|
|
- [ ] Payment webhook signatures verified (Stripe `stripe.webhooks.constructEvent`, Paddle equivalent)
|
|
- [ ] No endpoint bypasses billing verification (e.g., admin routes that skip plan checks)
|
|
- [ ] No race condition on session/resource creation that could allow free usage beyond limits (CWE-362)
|
|
|
|
### A05: Security Misconfiguration
|
|
- [ ] Default credentials changed
|
|
- [ ] Error messages don't expose internals
|
|
- [ ] Security headers present
|
|
- [ ] Unnecessary features disabled
|
|
|
|
### A06: Vulnerable Components
|
|
- [ ] Dependencies up to date
|
|
- [ ] Known vulnerabilities checked (npm audit)
|
|
- [ ] Only necessary packages included
|
|
|
|
### A07: Authentication Failures
|
|
- [ ] Strong password requirements
|
|
- [ ] Rate limiting on auth endpoints
|
|
- [ ] Session management secure
|
|
- [ ] MFA consideration
|
|
|
|
### A08: Data Integrity Failures
|
|
- [ ] Input validation
|
|
- [ ] Deserialization safety
|
|
- [ ] CI/CD pipeline security
|
|
|
|
### A09: Logging Failures
|
|
- [ ] Security events logged
|
|
- [ ] Log injection prevention
|
|
- [ ] Sensitive data not in logs
|
|
|
|
### A10: SSRF
|
|
- [ ] URL validation
|
|
- [ ] Whitelist allowed destinations
|
|
- [ ] Network segmentation
|
|
|

|
|
|
### Medium-Risk Issues
|
|
[Address in next sprint]

|
## Common Patterns to Check
|
|
|
|
```javascript
|
|
// BAD: SQL Injection
|
|
query = `SELECT * FROM users WHERE id = ${userId}`
|
|
|
|
// GOOD: Parameterized
|
|
query = `SELECT * FROM users WHERE id = $1`, [userId]
|
|
|
|
// BAD: XSS vulnerable
|
|
element.innerHTML = userInput
|
|
|
|
// GOOD: Safe
|
|
element.textContent = userInput
|
|
|
|
// BAD: Hardcoded secret
|
|
const API_KEY = "sk-abc123..."
|
|
|
|
// GOOD: Environment variable
|
|
const API_KEY = process.env.API_KEY
|
|
```
