{"id":"UBUNTU-CVE-2026-33414","details":"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.","modified":"2026-06-30T18:17:23.673990097Z","published":"2026-04-14T23:16:00Z","upstream":["CVE-2026-33414"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-33414"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-33414"},{"type":"REPORT","url":"https://github.com/containers/podman/security/advisories/GHSA-hc8w-h2mf-hp59"},{"type":"REPORT","url":"https://github.com/containers/podman/commit/571c842bd357ee626019ea97d030fb772fc654ed"}],"affected":[{"package":{"name":"podman","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/podman?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.1+ds1-1","5.4.2+ds1-1","5.4.2+ds1-2"],"ecosystem_specific":{"binaries":[{"binary_name":"podman","binary_version":"5.4.2+ds1-2"},{"binary_version":"5.4.2+ds1-2","binary_name":"podman-docker"},{"binary_name":"podman-remote","binary_version":"5.4.2+ds1-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-33414.json"}},{"package":{"name":"podman","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/podman?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2+ds1-2","5.7.0+ds2-3","5.7.0+ds2-3build1"],"ecosystem_specific":{"binaries":[{"binary_name":"podman","binary_version":"5.7.0+ds2-3build1"},{"binary_name":"podman-docker","binary_version":"5.7.0+ds2-3build1"},{"binary_name":"podman-remote","binary_version":"5.7.0+ds2-3build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-33414.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
