The host is installed with Atlassian Jira Server before 8.13.15, or 8.14.0 before 8.20.3 and is prone to a cross-site request forgery vulnerability. A flaw is present in the application which fails to properly handle an issue in the jira-importers-plugin. Successful exploitation could allow remote attackers to modify several resources (including CsvFieldMappingsPage.jspa and ImporterValueMappingsPage.jspa) via a Cross-Site Request Forgery (CSRF) vulnerability.
