CVE-2026-33414

Local SYSTEM code execution via unescaped image path

Published Apr 14, 2026 · Updated Apr 14, 2026

Command injection in Podman 4.8.0 through 5.8.1 allows local users to execute PowerShell commands through a crafted VM image path. The Hyper-V backend's resizeDisk function interpolates the path into a double-quoted Resize-VHD command, so PowerShell evaluates embedded $() subexpressions. The flaw is reachable only on Windows when the local user controls a machine name or image directory, and commands run with the Podman process's privileges, typically SYSTEM.
