"Puppetlabs reports :

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 & 2019.4.0, Puppet Server 6.9.1 & 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.");
