In the context of shopping carts, IDOR is often more financially damaging than SQLi. This occurs when the application exposes a direct reference to an internal object (like a database key) without performing an authorization check.
: Using a UNION operator (e.g., product.php?id=1 UNION SELECT 1, username, password FROM users ), a hacker can force the product page to display sensitive administrative credentials, customer credit card details, or personal data directly on the screen. How to Secure Your PHP Shopping Site

Because the code above directly injects the $_GET['id'] into the SQL query, a hacker does not have to send ?id=1 . They can send:
<?php // Assume $pdo is your database connection $id = filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT); if (!$id) die('Invalid product ID');
// token -> real order_id mapping $token = bin2hex(random_bytes(16)); $stmt = $conn->prepare("INSERT INTO access_tokens (token, order_id, user_id, expires) VALUES (?,?,?, NOW()+3600)"); // URL becomes: view_order.php?token=9f8d7c6b5a4...
To completely neutralize SQL Injection vulnerabilities, never concatenate user input directly into your SQL queries. Always use PDO (PHP Data Objects) and prepared statements to ensure the database treats the ID purely as a piece of data, not an executable command.
