Comment 9 Przemyslaw Roguski 2020-08-25 07:39:05 UTC 
Statement:

In Red Hat OpenShift Container Platform (RHOCP) the affected Kibana component is behind OpenShift OAuth authentication. This restricts access to the vulnerable Timelion Kibana component to authenticated users only, therefore the impact is Low.

Red Hat OpenShift Container Platform 4 delivers Kibana package where the Timelion tool is used, but due to the code changing to the container first content the kibana package is marked as wontfix. This may be fixed in the future.
