            Hello,

            The description is not clear at all regarding CVE Jira Service Management addon ? what does that mean is it an addon installed on JIRA server/Data center or the JIRA service management server/Data center(since the JIRA SM run a JIRA version) and could you explain further how the attacker can exploit ? there should be some W.A just incase one is not able to do upgrade. There is no explanation here https://www.atlassian.com/trust/security/advisories

            Kind regards,
            Moses
