How to fix?

Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 9.0.96, 10.1.31, 11.0.0 or higher.

Overview

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

Affected versions of this package are vulnerable to Uncaught Exception due to the custom Jakarta Authentication ServerAuthContext component which may throw an exception during the authentication process without setting an HTTP status to indicate failure. An attacker can gain unauthorized access by exploiting this unchecked error condition.

Note:

This is only exploitable if Tomcat is configured to use a custom Jakarta Authentication ServerAuthContext component that behaves in this way. According to the maintainers, no such cases are known.
