This allows any authenticated user to bypass experiment-level authorization controls on all trace operations, including reading, deleting, and modifying traces on experiments they do not have permission to access. The issue arises from the `_before_request` handler, which does not register authorization validators for trace endpoints, resulting in requests proceeding without validation. This vulnerability can expose sensitive data, destroy audit logs, and allow unauthorized modifications."}], "lastModified": "2026-07-06T16:46:06.477", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AD046C6D-0AF3-499E-A9D8-6BE7C0BEA278", "versionEndExcluding": "3.14.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@huntr.dev"}
