CVE-2019-8834
An attacker in a privileged network position may be able to bypass HSTS for a limited number of specific top-level domains previously not in the HSTS preload list.
Does this matter?
Lower severity and a low EPSS score (1.17%). Track it; it rarely justifies an emergency change on its own.
