{"id":"CVE-2026-57231","state":"PUBLISHED","title":"Podman: Malformed Image can trick podman run into leaking host environment variables into the container","description":"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.","publishedAt":"2026-06-26T16:29:02.092Z","updatedAt":"2026-06-27T02:41:58.574Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["podman-container-tools podman"],"affected":[{"vendor":"podman-container-tools","product":"podman","versions":[{"version":">= 1.8.1, < 5.8.4","status":"affected"}]}],"references":["https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68","https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050"],"weaknesses":["CWE-200","CWE-668"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/57xxx/CVE-2026-57231.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-57231","state":"PUBLISHED","datePublished":"2026-06-26T16:29:02.092Z","dateUpdated":"2026-06-27T02:41:58.574Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-24T02:21:33.811Z"},"containers":{"cna":{"title":"Podman: Malformed Image can trick podman run into leaking host environment variables into the container","descriptions":[{"lang":"en","value":"Podman is a tool for managing OCI containers and pods.
