Overview

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') when the Docker container serves as its own backend, which is an automatically generated route resulting from the Docker integration in the default configuration. This route can cause the CPU usage to spike to 100%, allowing an attacker to cause a denial of service by exploiting this behavior.
