Security Code Review

Review code for common security vulnerabilities and issues.

Check For

Injection Vulnerabilities

• SQL injection (unsanitized input in queries)
• Command injection (shell commands with user input)
• XSS (unescaped output in HTML/templates)
• Path traversal (user input in file paths)

Authentication & Authorization

• Missing auth checks on sensitive endpoints
• Hardcoded credentials or API keys
• Weak session management
• Improper access control

Secrets & Sensitive Data

• API keys, tokens, passwords in source code
• Credentials in configuration files
• Secrets in error messages or logs
• Sensitive data in URLs or query strings

Data Handling

• Sensitive data logged or exposed in errors
• Missing input validation
• Insecure deserialization
• Improper error handling revealing internals

Output Format

Report findings with: 1. **Location**: File and line number 2. **Issue**: What the vulnerability is 3. **Risk**: Severity (Critical/High/Medium/Low) 4. **Fix**: Recommended remediation

If no issues found, report "No security issues identified" with a brief summary of what was reviewed.
