CVE-2019-20403
The API in Atlassian Jira Server and Data Center before version 8.6.0 allows remote attackers to determine if a Jira project key exists or not via an information disclosure vulnerability.
Does this matter?
Lower severity and a low EPSS score (1.47%). Track it; it rarely justifies an emergency change on its own.
