Sensitive Data Security Check

Analyze PHP code for sensitive data exposure vulnerabilities.

Detection Patterns

1. Hardcoded Credentials

// CRITICAL: Hardcoded password
$pdo = new PDO($dsn, 'admin', 'SuperSecret123!');

// CRITICAL: API key in code
$apiKey = 'sk_live_abc123xyz789';
$stripe = new StripeClient($apiKey);

// CRITICAL: Hardcoded secret
define('JWT_SECRET', 'my-secret-key-123');
const ENCRYPTION_KEY = 'aes256-encryption-key';
