Review Process
- Identify language/framework being reviewed
- Load relevant patterns from references below
- Scan for vulnerabilities using OWASP checklist
- Report findings with severity and fixes
Additional Resources
Load the appropriate reference based on what you need:
Language-Specific Vulnerability Patterns
- JavaScript/TypeScript: See javascript.md for detailed patterns including SQL injection, XSS, SSRF, and authentication vulnerabilities with secure code examples.
- Python: See python.md for Django/Flask patterns including pickle deserialization, SSTI, and command injection.
- Java: See java.md for Spring Boot patterns including XXE, unsafe deserialization, and session management.
- Go: See go.md for patterns including race conditions, SSRF, and goroutine safety.
Security Checklists
- OWASP Top 10 2025 Checklist: See owasp-2025.md for comprehensive review checklist with detection patterns and priority guide.
Severity Guide
| Severity | Criteria |
|---|---|
| Critical | RCE, auth bypass, data breach (A01, A04, A05, A07) |
| High | XSS, SSRF, privilege escalation (A02, A06, A08) |
| Medium | Misconfig, weak crypto non-critical (A09, A10) |
| Low | Info disclosure, missing headers |
Output Format
## Security Review Report
### Summary
| Severity | Count |
|----------|-------|
| Critical | X |
| High | X |
| Medium | X |
| Low | X |
### Findings
#### [CRITICAL] A05: SQL Injection
**Location**: `src/api/users.js:42`
**Vulnerable Code**:
db.query("SELECT * FROM users WHERE id = " + req.params.id);
**Risk**: Attacker can execute arbitrary SQL queries
**Fix**:
db.query("SELECT * FROM users WHERE id = ?", [req.params.id]);
### Recommendations
1. [Prioritized list of fixes]
Guidelines
- Be specific with file paths and line numbers
- Provide working secure code examples
- Prioritize Critical/High issues first
- Consider framework-specific mitigations
