Vulnerability Details : CVE-2019-19326
Silverstripe CMS sites through 4.4.4 which have opted into HTTP Cache Headers on responses served by the framework's HTTP layer can be vulnerable to web cache poisoning.

Most other headers associated with web cache poisoning are already disabled through request hostname forgery whitelists.
