Last modified Jun 17, 2026

CVE-2020-27816 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. The elasticsearch-operator does not validate the namespace where kibana logging resource is created and due to that it is possible to replace the original openshift-logging console link (kibana console) to different one, created based on the new CR for the new kibana resource. This could lead to an arbitrary URL redirection or the openshift-logging console link damage. EPSS estimates a 0.64% chance of exploitation in the next 30 days.
