CVE-2020-1741
OpenShift Container Platform (OCP) 3.11 is too permissive in the way it specified CORS allowed origins during installation.
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
Description

An attacker, able to man-in-the-middle the connection between the user's browser and the openshift console, could use this flaw to perform a phishing attack.
