How to fix?

Upgrade puppet to version 6.13.0 or higher.

Overview

puppet is an automated configuration management tool.

Affected versions of this package are vulnerable to Improper Input Validation. Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the default node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting strict_hostname_checking = true in puppet.conf on your Puppet master.
