What are the potential security risks of allowing a script to access a user's hard drive?

Allowing a script to access a user's hard drive can pose significant security risks, such as exposing sensitive data, installing malware, or deleting important files. To mitigate these risks, it is important to carefully review and validate any scripts that require access to the hard drive, restrict access to only necessary files and directories, and regularly update security measures to prevent unauthorized access. 

// Example of restricting file access to a specific directory
$directory = '/path/to/allowed/directory/';
$file = $directory . 'file.txt';

if (strpos(realpath($file), $directory) !== 0) {
    die('Access denied');
}

// Proceed with accessing the file
$file_content = file_get_contents($file);
