{"id":"AZL-91448","summary":"CVE-2026-57231 affecting package podman 5.6.1-9","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":"2026-08-29T05:25:22Z","published":"2026-06-26T17:16:34Z","upstream":["CVE-2026-57231"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57231"}],"affected":[{"package":{"name":"podman","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/podman"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.6.1-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91448.json"}}],"schema_version":"1.9.0"}
