This happens because, although this type of vulnerability usually may lead to important consequences like web-cache poisoning or to access other vhosts that should not be exposed, the mirror-registry is running as a single vhost in a single pod and is not performing request caching thus not being vulnerable to web-cache poisoning. Additionally the usual password reset manipulation/phishing strategy that could be used with the host header injection is not possible here as such requests are handled by RHSSO instead of the mirror-registry itself.", "threat_severity": "Moderate"}
