A vulnerability scan showed that the JIRA Web server does not set an X-Frame-Options or Content-Security-Policy 'frame-ancestors' respose header in all content responses.
The solution was to return the X-Frame-Options or Content-Security-Policy (with the 'frame-ancestors' directive) HTTP header with the page's response.
This is way over my head. Is there something I can do to address this? I have seen others make adjustments to the web.xml file, but the other suggestions don't seem to apply to JIRA Software Server (v7.3)
