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.","published":"2026-04-14T22:42:19.822Z","modified":"2026-07-31T18:30:47.099686897Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/containers/podman/v4","fixedVersion":null},{"ecosystem":"Go","name":"github.com/containers/podman/v5","fixedVersion":"5.8.2"}],"fix":{"url":"https://github.com/containers/podman/commit/571c842bd357ee626019ea97d030fb772fc654ed","label":"containers/podman@571c842"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-33414.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:8211"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-33414"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33414.json"},{"type":"ADVISORY","url":"https://github.com/containers/podman/security/advisories/GHSA-hc8w-h2mf-hp59"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33414"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2458522"},{"type":"FIX","url":"https://github.com/containers/podman/commit/571c842bd357ee626019ea97d030fb772fc654ed"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:30:47.099686897Z"}}
