Descriptions

In WordPress through 4.9.2, 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.

En WordPress hasta la versión 4.9.2, los atacantes no autenticados puede provocar una denegación de servicio (consumo de recursos) utilizando una lista grande de archivos .js registrados (de wp-includes/script-loader.php) para construir una serie de peticiones para cargar cada archivo muchas veces.

In WordPress before 5.0, 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. It looks like most of the slowness was due to forcing PHP to repeatedly compress the output scripts, which was addressed in 5.0.

WordPress Core suffers from a load-scripts.php denial of service vulnerability.
