## Description

Puppet Server and PuppetDB provide useful performance and debugging
information via their metrics API endpoints. For PuppetDB this may contain
things like hostnames. Puppet Server reports resource names and titles for
defined types (which may contain sensitive information) as well as function
names and class names. Previously, these endpoints were open to the local
network. PE 2018.1.13 & 2019.5.0, Puppet Server 6.9.2 & 5.3.12, and
PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and
only allows /v2 access on localhost by default. This affects software
