CVE-2017-2296
In Puppet Enterprise 2017.1.x and 2017.2.1, using specially formatted strings with certain formatting characters as Classifier node group names or RBAC role display names causes errors, effectively causing a DOS to the service.
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
