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

Since Jenkins 2.340, symbol-based icons unescape previously escaped values of tooltip parameters.

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. Symbol-based icons no longer unescape values of tooltip parameters.
