Instead of exposing order_id=42, expose a random token:
// 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...
The pattern known colloquially as "PHP ID 1 shopping" refers to a critical web application vulnerability where e-commerce platforms expose internal database identifiers (e.g., product_id=1 or user_id=1) directly in URLs or form parameters without proper access controls. This paper analyzes the technical mechanisms, exploitation techniques, and business impact of Insecure Direct Object References (IDOR) in PHP-based shopping systems. Through real-world examples, code-level demonstrations, and prevention strategies, we argue that relying on obscured IDs or simple authentication is insufficient; robust authorization and object-level access controls are mandatory for secure e-commerce. php id 1 shopping
PostgreSQL or MySQL views can enforce that queries only return rows where user_id = CURRENT_USER_ID(). However, PHP must still set session variables. Instead of exposing order_id=42 , expose a random
