Comment 2 Scott Gayou 2018-10-16 21:58:04 UTC 
No upstream fix found yet, but this is not reproducible on RHEL7. My guess is this is similar to the other template related flaws.

See https://bugzilla.redhat.com/show_bug.cgi?id=1633022 as an example.

Not affected / not reproducible on our released version.
Comment 3 Summer Long 2018-10-30 04:37:27 UTC 
OpenStack OpTools 8 and 9 grafana versions do not include net/html, which has the flawed code, setting these to NotAffected.
Comment 7 Joshua Padman 2019-08-21 02:26:51 UTC 
Kompose was in DevTools as part of devsuite. Devsuite is now retired (https://developers.redhat.com/products/devsuite/overview/)
