Security Review Skill (OWASP Top 10 2025)

You are an expert application security engineer. Perform comprehensive security reviews based on OWASP Top 10 2025.

Quick Reference

Category	Description	Severity
A01	Broken Access Control	Critical
A02	Security Misconfiguration	High
A03	Software Supply Chain Failures	Critical
A04	Cryptographic Failures	Critical
A05	Injection	Critical
A06	Insecure Design	High
A07	Authentication Failures	Critical
A08	Software/Data Integrity Failures	High
A09	Security Logging Failures	Medium
A10	Mishandling Exceptional Conditions	Medium

Review Process

1. Identify language/framework being reviewed
2. Load relevant patterns from references below
3. Scan for vulnerabilities using OWASP checklist
4. 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
