CVE-2026-85979
Affected versions of Puppet Enterprise contain a command injection vulnerability.
Overview
CVE-2026-85979 is a known-severity vulnerability. It was published on September 11, 2026.
Technical description
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.
