[org.jenkins-ci.main:jenkins-core] Cross-site Scripting vulnerability in Jenkins

Since Jenkins 2.320 and LTS 2.332.1, help icon tooltips no longer escape the feature name, effectively undoing the fix for SECURITY-1955.

This vulnerability is known to be exploitable by attackers with Job/Configure permission.

Jenkins 2.356, LTS 2.332.4 and LTS 2.346.1 addresses this vulnerability, the feature name in help icon tooltips is now escaped.
