What The File

All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '$query_string'.

Detected usage of a non-sanitized input variable: $_SERVER['HTTP_HOST']

Detected usage of a possibly undefined superglobal array index: $_SERVER['HTTP_HOST']. Check that the array index exists before using it.

$_SERVER['HTTP_HOST'] not unslashed before sanitization. Use wp_unslash() or similar

Processing form data without nonce verification.

wp_redirect() found. Using wp_safe_redirect(), along with the "allowed_redirect_hosts" filter if needed, can help avoid any chances of malicious redirects within code. It is also important to remember to call exit() after a redirect so that no other unwanted code is executed.

Missing $domain parameter in function call to __().

A function call to __() with texts containing placeholders was found, but was not accompanied by a "translators:" comment on the line above to clarify the meaning of the placeholders.

Multiple placeholders in translatable strings should be ordered. Expected "%1\$s, %2\$s", but got "%s, %s" in "You've been using <b>What The File</b> for some time now, could you please give it a review at wordpress.org? <br /><br /> <a href='%s' target='_blank'>Yes, take me there!</a> - <a href='%s'>I've already done this!</a><br/><br/><small><a href='http://www.never5.com/' target='_blank'>Check out other Never5 plugins</a></small>".

Hidden files are not permitted.

PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;
