Hi Team !

Unauthenticated attackers can cause a denial of service (resource consumption) by using the large list of registered .js files (from wp-includes/script-loader.php) to construct a series of requests to load every file many times.
The vulnerability is registered as CVE-2018-6389.
WordPress allows users to load multiple JS files and CSS files through load-scripts.php files at once. However, the number and size of files are not restricted in the process of loading JS files, attackers can use this function to deplete server resources and launch denial of service attacks.
