{"id":"UBUNTU-CVE-2026-57231","details":"Podman is a tool for managing OCI containers and pods. From 1.8.1 until 5.8.4, a container image that contains a environment variable with just a key and no value can trick podman into passing that variable from the host into the container. This is made worse by the fact that using an asterisk (*) will cause podman to pass all host variables into the container. So essentially a malicious image can exfiltrate all podman environment variables that are set in the session from where the container is launched. This vulnerability is fixed in 5.8.4 and 6.0.0.","modified":"2026-06-29T23:18:11.461485779Z","published":"2026-06-26T17:16:00Z","upstream":["CVE-2026-57231"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57231"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57231"},{"type":"REPORT","url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68"},{"type":"REPORT","url":"https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050"}],"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_name":"podman-docker","binary_version":"5.4.2+ds1-2"},{"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-2026-57231.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_version":"5.7.0+ds2-3build1","binary_name":"podman-docker"},{"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-2026-57231.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
