CVE-2026-33414
PowerShell Command Injection in Podman HyperV Machine
Description
Podman is a tool for managing OCI containers and pods. Versions 4.8.0 through 5.8.1 contain a command injection vulnerability in the HyperV machine backend in pkg/machine/hyperv/stubber.go, where the VM image path is inserted into a PowerShell double-quoted string without sanitization, allowing $() subexpression injection. Because PowerShell evaluates subexpressions inside double-quoted strings before executing the outer command, an attacker who can control the VM image path through a crafted machine name or image directory can execute arbitrary PowerShell commands with the privileges of the Podman process. On typical Windows installations this means SYSTEM-level code execution, and only Windows is affected as the code is exclusive to the HyperV backend. This issue has been patched in version 5.8.2.

Action Type Old Value New Value Changed Translation Title: Podman de Containers, Description: Podman es una herramienta para gestionar contenedores OCI y pods. Las versiones 4.8.0 a la 5.8.1 contienen una vulnerabilidad de inyección de comandos en el backend de máquina HyperV en pkg/machine/hyperv/stubber.go, donde la ruta de la imagen de la VM se inserta en una cadena de PowerShell entre comillas dobles sin sanitización, permitiendo la inyección de subexpresiones $(). Debido a que PowerShell evalúa subexpresiones dentro de cadenas entre comillas dobles antes de ejecutar el comando externo, un atacante que puede controlar la ruta de la imagen de la VM a través de un nombre de máquina o directorio de imagen manipulado puede ejecutar comandos arbitrarios de PowerShell con los privilegios del proceso de Podman. En instalaciones típicas de Windows, esto significa ejecución de código a nivel de SYSTEM, y solo Windows se ve afectado ya que el código es exclusivo del backend de HyperV.
