CVE-2019-20402
Support zip files in Atlassian Jira Server and Data Center before version 8.6.0 could be downloaded by a System Administrator user without requiring the user to re-enter their password via an improper authorization vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.77%). Track it; it rarely justifies an emergency change on its own.
