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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"podman-container-tools","product":"podman","versions":[{"version":">= 1.8.1, < 5.8.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-27T02:41:47.348825Z","id":"CVE-2026-57231","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-200"},{"lang":"en","value":"CWE-668"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:podman_project:podman:*:*:*:*:*:*:*:*","versionStartIncluding":"1.8.1","versionEndExcluding":"5.8.4","matchCriteriaId":"C7D99B4B-8C58-47AD-BB57-A32E3044440F"},{"vulnerable":true,"criteria":"cpe:2.3:a:podman_project:podman:6.0.0:rc1:*:*:*:*:*:*","matchCriteriaId":"B8A3C450-FDBE-4DAD-A476-D09322BAA9FA"}]}]}],"references":[{"url":"https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68","source":"security-advisories@github.com","tags":["Patch","Third Party Advisory"]}]}
