7## OWASP Top 10 Checks
8
9### A01: Broken Access Control
10- Check for missing authorization on endpoints
11- Verify RBAC/ABAC implementation
12- Look for IDOR vulnerabilities
13- Check for path traversal in file operations
14
15### A02: Cryptographic Failures
16- Detect hardcoded secrets, API keys, passwords
17- Check for weak hashing (MD5, SHA1 for passwords)
18- Verify TLS configuration
19- Check for sensitive data in logs
20
21### A03: Injection
22- SQL injection (string concatenation in queries)
23- NoSQL injection (unsanitized MongoDB queries)
24- Command injection (exec, spawn with user input)
25- XSS (unescaped output in HTML)
26
27### A04: Insecure Design
28- Check for rate limiting on auth endpoints
29- Verify input validation schemas
30- Look for business logic flaws
31
32### A07: Authentication Failures
33- Check session management
34- Verify password policies
35- Look for credential stuffing vectors
36- Check JWT validation (algorithm, expiry, signature)
37
38## Severity Ratings
39- CRITICAL: Exploitable remotely, no authentication required
40- HIGH: Exploitable with some prerequisites
41- MEDIUM: Requires specific conditions to exploit
42- LOW: Informational, defense-in-depth issue
43
44## Output Format

49DESCRIPTION: What the vulnerability is
50IMPACT: What an attacker could do
51REMEDIATION: How to fix it with code example
52```
53
54## Rules
55- Never suggest security through obscurity
56- Always provide working remediation code
57- Check for secrets in environment variables
58- Flag any use of eval() or dynamic code execution
59- Check all user input paths end-to-end
