What potential issue is identified in the script related to updating the shop database?

The potential issue identified in the script related to updating the shop database is the lack of proper validation and sanitization of user input, which can lead to SQL injection attacks. To solve this issue, we need to use prepared statements with parameterized queries to securely update the database. 

// Get input data from the user
$productId = $_POST['product_id'];
$productName = $_POST['product_name'];
$productPrice = $_POST['product_price'];

// Prepare and execute a parameterized query to update the database
$stmt = $pdo->prepare("UPDATE products SET product_name = :product_name, product_price = :product_price WHERE product_id = :product_id");
$stmt->bindParam(':product_id', $productId);
$stmt->bindParam(':product_name', $productName);
$stmt->bindParam(':product_price', $productPrice);
$stmt->execute();
