Puppet Enterprise

Cleartext storage of sensitive parameters in Puppet's resource_api module (versions 1.5.0-1.9.1 and 2.0.0) causes passwords and other credential values to persist unmasked in the Puppet agent's local transaction state cache. The sensitive flag - intended to prevent exactly this exposure - is silently dropped during resource_api parameter processing, meaning any resource type built on this API and declaring sensitive parameters leaks those values to the cache filesystem. No public exploit exists and this is not listed in CISA KEV, but the confidentiality impact is high for environments where Puppet manages secrets such as database passwords or API tokens.
