In what scenarios might a PHP script automatically reset CHMOD settings to 644, and how can this issue be addressed?

If a PHP script is automatically resetting CHMOD settings to 644, it may be due to a security vulnerability or a misconfiguration in the script. To address this issue, you should review the code to ensure that proper file permissions are being set and that there are no vulnerabilities that could be exploited by malicious actors. 

// Example code to set file permissions to 644
$file = 'example.txt';
$permissions = 0644; // Octal value for 644

if (file_exists($file)) {
    chmod($file, $permissions);
    echo "File permissions set to 644 for $file";
} else {
    echo "File does not exist";
}
