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.","state":0,"publishedAt":"2026-06-26T16:29:02.092+00:00","modifiedAt":"2026-06-27T02:41:58.574+00:00","affected":[{"ecosystem":"Vendor product","name":"podman","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"podman-container-tools\",\n                    \"product\": \"podman\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.8.1, < 5.8.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68","https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57231","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57231","identifiers":["CVE-2026-57231"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
