CVE-2026-33414 PowerShell Command Injection in Podman HyperV Machine

What is CVE-2026-33414?

CVE-2026-33414 is a medium-severity command injection vulnerability in containers podman, published on 14 Apr 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-94, CWE-78
