在WordPress ROOT中找到一个隐藏的php FILE /（CODE）。 这是一个后门吗？ 我应该删除吗？

Question

I found a hidden PHP file in my WordPress ROOT. Can someone please confirm if its a Backdoor and I should delete it or is this file safe?

The file name is:

.wysiwygPro_preview_2cc37e731786ff9b24157cd9f049b9cb.php

And its contet:

<?php
if ($_GET['randomId'] != "h6wErVoQiTtcfJOQAXxRY56_1NdgoGfVy_NpD4ecgtbBjp6URh8lF") {
    echo "Access Denied";
    exit();
}

 display the HTML code:
echo stripslashes($_POST['wproPreviewHTML']);

?>

Can someone please tell me if its dangerous to have such code on server or its safe? Thank you for your comments and thoughts on this code :)

Answer 1

It's a file generated by the wysiwyg editor in your cPanel hosting - it's not a hack or a backdoor.

They're perfectly safe to delete if you want to free up space.
