{"cve":"CVE-2026-33414","nvd":{"published":"2026-04-14T23:16:27.987","modified":"2026-07-24T23:10:00.563","status":"Modified","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.","cvss_v4":{"vector":"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","score":4.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78","CWE-94"],"references":["https://github.com/containers/podman/commit/571c842bd357ee626019ea97d030fb772fc654ed","https://github.com/containers/podman/security/advisories/GHSA-hc8w-h2mf-hp59","https://access.redhat.com/errata/RHSA-2026:8211","https://access.redhat.com/security/cve/CVE-2026-33414","https://bugzilla.redhat.com/show_bug.cgi?id=2458522"],"products":["podman_project:podman"],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-33414","score":0.00607,"percentile":0.49075,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hc8w-h2mf-hp59","url":"https://osv.dev/vulnerability/GHSA-hc8w-h2mf-hp59","summary":"PowerShell Command Injection in Podman HyperV Machine","modified":"2026-09-10T03:51:01.905738307Z","packages":[{"ecosystem":"Go","name":"github.com/containers/podman/v4","purl":"pkg:golang/github.com/containers/podman/v4","ranges":[">=4.8.0 <=4.9.5"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containers/podman/v5","purl":"pkg:golang/github.com/containers/podman/v5","ranges":["<5.8.2"],"fixed":["5.8.2"]}]},{"id":"GO-2026-5421","url":"https://osv.dev/vulnerability/GO-2026-5421","summary":"PowerShell Command Injection in Podman HyperV Machine in github.com/containers/podman","modified":"2026-06-25T23:01:12.563671841Z","packages":[{"ecosystem":"Go","name":"github.com/containers/podman","purl":"pkg:golang/github.com/containers/podman","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containers/podman/v2","purl":"pkg:golang/github.com/containers/podman/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containers/podman/v3","purl":"pkg:golang/github.com/containers/podman/v3","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containers/podman/v4","purl":"pkg:golang/github.com/containers/podman/v4","ranges":[">=4.8.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/containers/podman/v5","purl":"pkg:golang/github.com/containers/podman/v5","ranges":["<5.8.2"],"fixed":["5.8.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
