Andrew, this has not been addressed in Jira 7.13.5, the latest shipping version of 7.x. We are upgrading to that now to address a critical vulnerability, but I see that it still has Tomcat 8.5.35.

Please reopen and escalate this request to address some of the vulnerabilities noted in https://www.cvedetails.com/vulnerability-list/vendor_id-45/product_id-887/version_id-282038/Apache-Tomcat-8.5.35.html. I am relieved to see that the worst of those exploits, CVE-2019-0232, is limited to Windows, because my own instances run on Linux, but that won't make Information Security folks any less concerned about running obsolete middleware.
