How to fix?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 8.5.96, 9.0.83, 10.1.16, 11.0.0-M10 or higher.

Overview

org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.

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