Puppet Enterprise
Monthly
Command injection in Puppet Enterprise's java_keystore_passwd parameter handling allows authenticated Puppet administrators to execute arbitrary OS commands with root privileges. The parameter value is passed to a shell execution context without sanitization, enabling full system compromise from a high-trust but network-accessible role. No public exploit code or CISA KEV listing has been identified at time of analysis.
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.
OS command injection (CWE-78) in Puppet Enterprise allows authenticated users holding node group editing permissions to craft a malicious class parameter that executes arbitrary commands as root on the primary Puppet server. Affected versions span 2018.1.8 through 2023.8.3 and 2025.3; fixed releases 2023.8.4 and 2025.4.0 are available from the vendor.
