The danger is not the id itself; it is . If the developer assumes the id will always be a safe number (like 123 ) and directly inserts it into an SQL query without validation, the application is vulnerable.

// File: index.php (Router) // Via .htaccess: RewriteRule ^post/([0-9]+)$ index.php?id=$1 [QSA] $id = filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT); $stmt = $conn->prepare("SELECT * FROM posts WHERE id = ?"); $stmt->bind_param("i", $id); $stmt->execute(); inurl index.php%3Fid=

For security professionals: This search string remains one of the most reliable ways to find low-hanging fruit during a bug bounty hunt. The danger is not the id itself; it is

// SAFE CODE $id = $_GET['id']; $stmt = $conn->prepare("SELECT * FROM products WHERE id = ?"); $stmt->bind_param("i", $id); // "i" forces the input to be an integer. $stmt->execute(); Refactor your code

While the URL structure itself is a standard method for passing data in PHP, it is a frequent target for identifying sites susceptible to SQL Injection (SQLi) and other security flaws. What Does This Keyword Mean? The query is composed of two main parts:
