How to fix?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

Overview

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper handling of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a specially crafted, invalid trailer header. This could lead to request smuggling when the server is behind a reverse proxy.
