CVE-2018-3830
Kibana versions 5.3.0 to 6.4.1 had a cross-site scripting (XSS) vulnerability via the source field formatter that could allow an attacker to obtain sensitive information from or perform destructive actions on behalf of other Kibana users.
Does this matter?
Lower severity and a low EPSS score (1.63%). Track it; it rarely justifies an emergency change on its own.
