CVE-2026-85979: Command Injection in Puppet Enterprise
Affected versions of Puppet Enterprise contain a command injection vulnerability. An authenticated user with Puppet administrative privileges can inject arbitrary shell commands by providing a specially crafted value for this parameter, which is passed to a shell execution context without sufficient sanitization. Because the resulting commands are executed with root privileges, successful exploitation can lead to full compromise of the affected system.
It affects Puppet Enterprise 2023.8.0 through 2023.8.10 and Puppet Enterprise 2025.0.0 through 2025.11.2.
This has been resolved in Puppet Enterprise 2023.8.11 and Puppet Enterprise 2025.11.3.

Frequently Asked Questions
Who can exploit this issue?
Exploitation requires an authenticated user with Puppet administrative privileges. The issue is therefore most relevant where administrative access is broadly assigned, shared, or could be obtained by an attacker.
What is the impact of successful exploitation?
A crafted java_keystore_passwd value can cause arbitrary shell commands to run as root. Successful exploitation can fully compromise the affected system.
What input should be reviewed while investigating possible exposure?
Review use and changes to the java_keystore_passwd parameter, particularly values supplied by Puppet administrators. Specially crafted values for this parameter are the injection vector described.
