CVE-2015-4100
Puppet Enterprise 3.7.x and 3.8.0 might allow remote authenticated users to manage certificates for arbitrary nodes by leveraging a client certificate trusted by the master, aka a "Certificate Authority Reverse Proxy Vulnerability."
Does this matter?
Lower severity and a low EPSS score (0.70%). Track it; it rarely justifies an emergency change on its own.
