WordPress Core < 5.0 - Denial of Service

7.5
Uncontrolled Resource Consumption
CVE CVE-2018-6389
CVSS 7.5 (High)
Publicly Published February 5, 2018
Last Updated February 6, 2024
Researcher Barak Tawily

Description

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.
