PHP EUVD-2025-21046

Immediate actions: (1) Apply input validation: implement parameterized prepared statements using mysqli_prepare() or PDO prepared statements to eliminate SQL injection, (2) Code fix example—replace direct concatenation in /success.php with prepared statements: $stmt = $conn->prepare('SELECT * FROM orders WHERE id = ?'); $stmt->bind_param('i', $_GET['ID']); $stmt->execute();, (3) Input sanitization: whitelist/validate ID parameter as integer-only using intval() or type casting, (4) Web Application Firewall (WAF) rule: deploy ModSecurity or similar to block SQL metacharacters in GET parameters, (5) No official patch identified—contact code-projects maintainers immediately or migrate to maintained fork if available. Workaround: Restrict /success.php access via authentication token validation until patched.
