What are the potential security risks of manipulating DWG files with PHP?

Manipulating DWG files with PHP can pose security risks such as allowing malicious code execution, exposing sensitive information, or potentially compromising the server. To mitigate these risks, it is important to validate and sanitize user inputs, restrict file permissions, and use secure file handling practices. 

// Example of secure file handling when manipulating DWG files with PHP

$filename = "example.dwg";

// Validate file extension
$allowed_extensions = ['dwg'];
$file_extension = pathinfo($filename, PATHINFO_EXTENSION);
if (!in_array($file_extension, $allowed_extensions)) {
    die("Invalid file extension.");
}

// Restrict file permissions
chmod($filename, 0600);

// Perform DWG file manipulation here
// Remember to validate and sanitize user inputs before processing them
