{"id":"ALPINE-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":"2026-11-03T06:32:58.078810751Z","published":"2026-06-26T17:16:34.697Z","upstream":["CVE-2026-57231"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-57231"}],"affected":[{"package":{"name":"podman","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/podman?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.8.1"},{"fixed":"5.8.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-57231.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
