Doc Text:	A session fixation vulnerability has been identified in Apache Tomcat, affecting its rewrite functionality. If the rewrite valve is enabled for a web application, an attacker can craft a specific URL. If a victim clicks on this malicious URL, their subsequent interaction with the resource will occur within the context of the attacker's session. This could allow an attacker to hijack the victim's session and perform actions on their behalf.	Story Points:	---

Can we please have a fix for the Red Hat Enterprise Linux 8?

Rebasing to 9.0.110 as for RHEL 9 would be fantastic.

If at the same time the dependency on OpenJDK 1.8.0 could also be removed, that would be great!
