Versions of Puppet Enterprise prior to 2016.4.5 or 2017.2.1 failed to mark MCollective server private keys as sensitive (a feature added in Puppet 4.6), so key values could be logged and stored in PuppetDB. These releases use the sensitive data type to ensure this won't happen anymore.
Add your gear to cvedb and we'll alert you only when puppet ships something exploited.
