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.","published_at":"2026-07-02T07:32:58.308000Z","last_modified_at":"2026-07-06T16:46:06.477000Z","cvss_v3_score":8.1,"cvss_v3_vector":"CVSS:3.0/AV:N/AC:L/PR:L/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-284"],"nvd_references":["https://huntr.com/bounties/b00c3ddd-373e-492f-9bf0-41a28bb21ed5","https://github.com/mlflow/mlflow/commit/f9b1eb510478570609ef451984a255775aa4b937"],"vuln_status":"Analyzed","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":"2026-07-02T09:22:34.988519Z","updated_at":"2026-07-07T03:28:50.836627Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.0","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":"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":"3.14.0","version_end_inclusive":false,"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":"3.14.0","version_end_inclusive":false,"cpe23_uri":"cve5:mlflow:mlflow-mlflow:unspecified:3.14.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/b00c3ddd-373e-492f-9bf0-41a28bb21ed5","source_type":"MISC","tags":[]},{"url":"https://github.com/mlflow/mlflow/commit/f9b1eb510478570609ef451984a255775aa4b937","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-07-02T07:32:58.308000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-07-04T02:42:58.941961Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-04T02:42:58.941961Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-04T02:42:58.941961Z","label":"SSVC decision revised","source":"vulnrichment"}]}
