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."}], "lastModified": "2026-06-04T15:41:46.770", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C1C49CD5-5BB0-422B-9A71-5A6832DF6713", "versionEndIncluding": "3.10.1"}], "operator": "OR"}]}], "sourceIdentifier": "security@huntr.dev"}
