Overview

Spring Cloud Gateway

In spring cloud gateway versions prior to 3.1.1+ and 3.0.7+ , applications are vulnerable to a code injection attack when the Gateway Actuator endpoint is enabled, exposed and unsecured.

A remote attacker could make a maliciously crafted request that could allow arbitrary remote execution on the remote host.
