h3. Issue Summary

Jira uses {{Bouncy Castle}} library in version 1.50 thatโ€™s vulnerable to 10 CVEs:

[https://www.cvedetails.com/cve/CVE-2015-7940/]
[https://www.cvedetails.com/cve/CVE-2016-1000338/]
[https://www.cvedetails.com/cve/CVE-2016-1000339/]
[https://www.cvedetails.com/cve/CVE-2016-1000341/]
[https://www.cvedetails.com/cve/CVE-2016-1000342/]
[https://www.cvedetails.com/cve/CVE-2016-1000343/]
[https://www.cvedetails.com/cve/CVE-2016-1000344/]
[https://www.cvedetails.com/cve/CVE-2016-1000345/]
[https://www.cvedetails.com/cve/CVE-2016-1000346/]
[https://www.cvedetails.com/cve/CVE-2016-1000352/]

It is not clear if any of the vulnerabilities can actually be abused by an attacker.

The library should be updated to at least version 1.56 to fix those CVEs.
However, that version has other known vulnerabilities, so itโ€™s recommended to update it to at least 1.61.
h3. Workaround
There is no known workaround for this behavior.
