The VM image path is inserted into a PowerShell double-quoted string without sanitization, allowing `$()` subexpression injection.\n\n## Affected Code\n\n**File**: `pkg/machine/hyperv/stubber.go:647`\n\n```go\nresize := exec.Command(\"powershell\", []string{\n    \"-command\",\n    fmt.Sprintf(\"Resize-VHD \\\"%s\\\" %d\", imagePath.GetPath(), newSize.ToBytes()),\n}...)\n```\n\n\n\n## Root Cause\n\nPowerShell evaluates `$()` subexpressions inside double-quoted strings before executing the outer command. The `fmt.Sprintf` call places the user-controlled image path directly into double quotes without escaping or sanitization.\n\n## Impact\n\nAn 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 the Windows host. On typical Windows installations, this means SYSTEM-level code execution.\n\n\n## Patch\n\nhttps://github.com/containers/podman/commit/571c842bd357ee626019ea97d030fb772fc654ed\n\nThe affected code is only used on Windows, all other operating systems are not affected by this and can thus ignore the CVE patch.\n\n## Credit\n\nWe like to thank Sang-Hoon Choi (@KoreaSecurity) for reporting this issue to us.",
