In the given code snippet, what potential security risks are present when using the split() function in PHP to parse data from a text file?

Using the split() function in PHP to parse data from a text file can potentially lead to security risks like allowing for code injection attacks through specially crafted input data. To mitigate this risk, it is recommended to use more secure methods like regular expressions or specific parsing functions that can handle the data safely. 

$fileContents = file_get_contents('data.txt');
$dataLines = explode("\n", $fileContents);

foreach ($dataLines as $line) {
    $dataArray = explode(',', $line);
    
    // Process the data array safely
}
