Security Review

Perform a security-focused code review.

Focus Areas

1. Injection Vulnerabilities

• SQL injection
• Command injection
• XSS (Cross-Site Scripting)
• LDAP injection
• XML injection

2. Authentication & Authorisation

• Hardcoded credentials
• Weak password handling
• Missing auth checks
• Privilege escalation paths

3. Data Exposure

• Sensitive data in logs
• PII in error messages
• Secrets in version control
• Insecure data transmission

4. Cryptography

• Weak algorithms (MD5, SHA1 for security)
• Hardcoded keys/IVs
• Insecure random number generation

5. Dependencies

• Known vulnerable packages
• Outdated dependencies

Process

1. Get diff for specified range
2. Scan for security patterns
3. Check for common vulnerabilities
4. Report findings with severity

Patterns to Check

Go

// SQL injection
db.Query("SELECT * FROM users WHERE id = " + id)

// Command injection
exec.Command("bash", "-c", userInput)

// Hardcoded secrets
apiKey := "sk_live_..."

PHP

// SQL injection
$db->query("SELECT * FROM users WHERE id = $id");

// XSS
echo $request->input('name');

// Command injection
shell_exec($userInput);

Output Format

## Security Review

### Critical
- **file:line** - SQL Injection: User input directly in query

### High
- **file:line** - Hardcoded API key detected

### Medium
- **file:line** - Missing CSRF protection

### Low
- **file:line** - Debug endpoint exposed

---
**Summary**: X critical, Y high, Z medium, W low
