Description Pedro Sampaio 2021-03-25 14:53:43 UTC

A flaw in Kibana’s session timeout was discovered where the xpack.security.session.idleTimeout setting is not being respected. This was caused by background polling activities unintentionally extending authenticated users sessions, preventing a user session from timing out.

Comment 2 Przemyslaw Roguski 2021-04-02 15:23:12 UTC

Statement:

In OpenShift Container Platform (OCP) the kibana components have X-Pack security features disabled by default. The X-Pack plugin can be used only is an enterprise version [1].
Hence the open source version is unaffected by this vulnerability.

Cluster Logging does not ship Kibana with X-Pack installed, not just disabled, it isn't even able to be turned on.
