Affected: Red Hat OpenShift Container Platform 4.12, Red Hat OpenShift Container Platform 4.13, Red Hat OpenShift Container Platform 4.14, Red Hat OpenShift Container Platform 4.15, Red Hat OpenShift Container Platform 4.16, Red Hat OpenShift Container Platform 4.17, Red Hat OpenShift Container Platform 4.18, Red Hat OpenShift Container Platform 4.19, Red Hat OpenShift Container Platform 4.20, Red Hat OpenShift Container Platform 4.21 and 1 more

A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys (X-Forwarded-User) but does not strip underscore-variant keys (X_Forwarded_User) from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing an authenticated low-privilege user to smuggle a forged identity that may override the legitimate authenticated identity in the upstream application.
