CVE-2021-27026

Sensitive plan-parameter disclosure through service logs

Published Nov 18, 2021 · Updated Aug 3, 2024

Sensitive-data exposure in Puppet Enterprise and Puppet Connect allows local users with high privileges to read plan parameters from logs. The pe-bolt-server and pe-ace-server services write parameters marked sensitive at INFO, their default log level. Access requires local high privileges, and the impact is limited to the confidentiality of logged plan inputs.
