Specifically, the use of `tarfile.extractall` without path validation enables crafted tar.gz files containing `..` or absolute paths to escape the intended extraction directory. This issue affects the latest version of MLflow and poses a high/critical risk in scenarios involving multi-tenant environments or ingestion of untrusted artifacts, as it can lead to arbitrary file overwrites and potential remote code execution.","published_at":"2026-03-18T22:06:47.300000Z","last_modified_at":"2026-07-15T02:17:19.360000Z","cvss_v3_score":8.1,"cvss_v3_vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-22"],"nvd_references":["https://huntr.com/bounties/09856f77-f968-446f-a930-657d126efe4e"],"vuln_status":"Modified","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":"2026-06-24T00:09:39.878444Z","updated_at":"2026-07-15T15:32:50.779815Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"A","value_label":"Adjacent"},{"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":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"lfprojects","vendor_name":"lfprojects","product_slug":"mlflow","product_name":"MLflow","version_start":null,"version_start_inclusive":null,"version_end":"3.10.1","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*"},{"vendor_slug":"mlflow","vendor_name":"mlflow","product_slug":"mlflow-mlflow","product_name":"mlflow/mlflow","version_start":"unspecified","version_start_inclusive":true,"version_end":"latest","version_end_inclusive":true,"cpe23_uri":"cve5:mlflow:mlflow-mlflow:unspecified:latest"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/09856f77-f968-446f-a930-657d126efe4e","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-03-18T22:06:47.300000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:41:39.863887Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:41:39.863887Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:41:39.863887Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-06-30T04:46:12.618760Z","label":"CVSS score revised","source":"vulnrichment"}]}
