How to fix?

Upgrade org.apache.tomcat:tomcat to version 8.5.5 or higher.

Overview

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Improper Access Control. It did not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an httpoxy issue.
