CVE-2017-18039
The IncomingMailServers resource in Atlassian Jira from version 6.2.1 before version 7.4.4 allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the messagesThreshold parameter.
Does this matter?
Lower severity and a low EPSS score (1.11%). Track it; it rarely justifies an emergency change on its own.
