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.","published_at":"2026-06-26T16:29:02.092000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-200","CWE-668"],"nvd_references":["https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68","https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:42.709123Z","updated_at":"2026-06-28T23:30:57.805291Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"podman-container-tools","vendor_name":"podman-container-tools","product_slug":"podman","product_name":"podman","version_start":">= 1.8.1, < 5.8.4","version_start_inclusive":true,"version_end":">= 1.8.1, < 5.8.4","version_end_inclusive":true,"cpe23_uri":"cve5:podman-container-tools:podman:>= 1.8.1, < 5.8.4:>= 1.8.1, < 5.8.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/podman-container-tools/podman/security/advisories/GHSA-4hq8-gpf5-8p68","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/podman-container-tools/podman/commit/6c431b73dbf8e4b20b778644d7a80caebdb75050","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-26T16:29:02.092000Z","label":"CVE published","source":null}]}
