VulniPulse record published Record updated
Summary
In MLflow versions prior to 3.14.0, when running with authentication enabled, the trace API endpoints lack proper authorization validators. 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.
A flaw was found in MLflow. This is due to missing authorization validators, allowing unauthorized reading, deleting, and modifying of traces.
This Important flaw in MLflow, as deployed in Red Hat OpenShift AI, allows an authenticated user to bypass experiment-level authorization controls on trace API endpoints. This enables unauthorized access, modification, and deletion of sensitive trace data, impacting the confidentiality and integrity of machine learning experiment results within the platform.
The vulnerability specifically affects the `rhoai/odh-mlflow-rhel9` component. Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
Weakness: CWE-425. Red Hat lists Red Hat OpenShift AI (RHOAI) as not affected.
