S6 — Security Review

Perform a security-focused review of: $ARGUMENTS

If no target is specified, review the entire codebase.

Review Checklist

Critical — Check for These First

1. Hardcoded Secrets: API keys, tokens, passwords in source code
2. Injection Vulnerabilities: SQL injection, command injection, code injection
3. Insecure Authentication: Weak comparison, missing rate limiting, plain-text passwords
4. Input Validation Gaps: Unvalidated user input passed to sensitive operations

High Priority

5. Unsafe Deserialization: pickle.loads, yaml.load without SafeLoader
6. Path Traversal: User input in file paths without sanitization
7. Information Disclosure: Stack traces, debug info, verbose error messages
8. Missing Access Control: Operations without authorization checks

Medium Priority

9. Timing Attacks: String comparison of secrets using == instead of hmac.compare_digest
10. Dependency Issues: Known vulnerable packages, unpinned versions

Report Format

For each finding, report:

[SEVERITY: CRITICAL/HIGH/MEDIUM/LOW] Title
  File: file_path:line_number
  Issue: What the vulnerability is
  Impact: What an attacker could do
  Fix: How to remediate

End with a severity summary and prioritized fix list.
