Name of the Vulnerable Software and Affected Versions Kibana versions prior to 7.12.0 Kibana versions prior to 6.8.15

Description A flaw in the 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.

Recommendations For versions prior to 7.12.0, update to version 7.12.0 or later to resolve the issue. For versions prior to 6.8.15, update to version 6.8.15 or later to resolve the issue. As a temporary workaround, consider restricting background polling activities to minimize the risk of exploitation.
