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.

The version of Podman installed on the remote Windows host is prior to 5.8.2. It is, therefore, affected by a command injection vulnerability in the HyperV machine backend.

  - A command injection vulnerability exists in Podman's HyperV machine backend. The VM image path is inserted into a     PowerShell double-quoted string without sanitization, allowing $() subexpression injection. An attacker who can     control the VM image path can execute arbitrary PowerShell commands with the privileges of the Podman process on     the Windows host. (CVE-2026-33414)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
