I suspect that my app, Jenkins Integration for Jira, is also effected by this change. Just yesterday a user of the app informed me that links to there Jenkins instance from within Jira are not working as expected.
Before the app would in its panels also generate links to jobs and builds in Jenkins, and these links would open in a new window.
But since a couple of days all these links open with connection refused errors.
Looking into the issue is seems that the
X-Frame-Options header with value
sameorigin is the cause of the issue. Changing the link target from
_top fixes the issue in that the links work again, but now the user is navigating away from Jira which I whether not do.
Is there a workaround available?
I also tried a redirect service endpoint but with no success.
