yes it is suspicious and spreading malware, it is not including JS file, but it is calling PHP script on other site.

That script is also stealing your cookies.

Ask your host to increase PHP memory limit, It is a PHP setting.

67108864 Bytes is just 67MB so setting up memory limit to anything more than 100M will do.

Which WordPress version; Which PHP version installed on the server?

Use admin_post while submitting a form in wp-admin area;

admin_post_* works well when user is logged in and has admin access, admin_post_nopriv_* is for guest users.

But when you want to submit form in front end (for logged or non logged in users)

You should use wp_ajax_* and wp_ajax_nopriv_* hooks, It works exactly same as admin_post.

You will also need to change your form action to admin_url('admin-ajax.php') which is /wp-admin/admin-ajax.php wp_ajax is used for ajax form submission but you can also use it for normal form submissions.

While doing normal form submission please also remember to redirect page at the end of your function. Avoid using PHP header function use wp_redirect instead.
