The authorization logic does not enforce resource-level permission checks for `/mlflow-artifacts/mpu/*` endpoints, enabling attackers to overwrite artifacts belonging to other users. This can lead to unauthorized cross-user writes, model supply chain poisoning, and arbitrary code execution when compromised models are loaded. The issue is resolved in version 3.10.0.","published_at":"2026-05-25T06:00:34.002000Z","last_modified_at":"2026-07-21T19:10:00.107000Z","cvss_v3_score":9.0,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","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-862","CWE-1220"],"nvd_references":["https://huntr.com/bounties/65beb119-d3e0-4e03-af2f-fa98f78f83dc","https://github.com/mlflow/mlflow/commit/d7290811d8f3c95366d80109424edc1fb1ad966f"],"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":"2026-07-21T21:45:23.985996Z"},"effective_severity":"CRITICAL","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":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"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":"3.10.0","version_end_inclusive":false,"cpe23_uri":"cve5:mlflow:mlflow-mlflow:unspecified:3.10.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/65beb119-d3e0-4e03-af2f-fa98f78f83dc","source_type":"MISC","tags":[]},{"url":"https://github.com/mlflow/mlflow/commit/d7290811d8f3c95366d80109424edc1fb1ad966f","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-05-25T06:00:34.002000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","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"}]}
