Credentials in git history (git log -p -S 'pattern')
.env files accidentally committed
Authentication & Authorization
Missing auth checks on API endpoints
Session management vulnerabilities (predictable IDs, no expiry)
OAuth flow issues (missing state parameter, open redirects, token leaks)
Privilege escalation paths (account switching without validation)
Input Validation
SQL/GAQL injection (unparameterized user input in queries)
Path traversal (.. in file paths)
CORS misconfiguration (wildcard origins in production)
XSS vectors in user-generated content
Error Handling
Internal details leaked in error messages
Stack traces exposed to clients
Verbose error codes revealing implementation
Encryption
Weak key derivation (padEnd instead of PBKDF2)
Fallback to insecure algorithms (XOR)
Missing encryption for sensitive data at rest
Rate Limiting
Missing rate limits on authentication endpoints
No abuse prevention on public APIs
Severity Ratings
Critical: Immediate exploitation possible, data breach risk
High: Exploitable with moderate effort, significant impact
Medium: Requires specific conditions, limited impact
Low: Best practice violation, minimal direct risk
