{"id":"DEBIAN-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":"2026-08-30T22:00:07.729114809Z","published":"2026-06-26T17:16:34.697Z","upstream":["CVE-2026-57231"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-57231"}],"affected":[{"package":{"name":"podman","ecosystem":"Debian:13","purl":"pkg:deb/debian/podman?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1","5.8.1+ds1-2","5.8.1+ds1-3","5.8.2+ds1-1","5.8.2+ds1-2","5.8.2+ds1-3","5.8.3+ds1-1","5.8.4+ds1-1","5.8.4+ds1-2","5.8.6+ds1-1","5.8.6+ds1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57231.json"}},{"package":{"name":"podman","ecosystem":"Debian:14","purl":"pkg:deb/debian/podman?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.8.4+ds1-1"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1","5.8.1+ds1-2","5.8.1+ds1-3","5.8.2+ds1-1","5.8.2+ds1-2","5.8.2+ds1-3","5.8.3+ds1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57231.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
