CVE-2025-15381
Unauthorized Access to Tracing and Assessment Endpoints in mlflow/mlflow
Overview
Description

In the latest version of mlflow/mlflow, when the `basic-auth` app is enabled, tracing and assessment endpoints are not protected by permission validators. This allows any authenticated user, including those with `NO_PERMISSIONS` on the experiment, to read trace information and create assessments for traces they should not have access to. This vulnerability impacts confidentiality by exposing trace metadata and integrity by allowing unauthorized creation of assessments. Deployments using `mlflow server --app-name=basic-auth` are affected.

Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 134c704f-9b21-4f2e-91b3-4a467353bcc0
CVSS 3.0 HIGH [email protected]
CVSS 3.1 HIGH [email protected]
CVSS 3.1 HIGH 0b0ca135-0b70-47e7-9f44-1890c2a1c46c
Solution
Restrict access to tracing and assessment endpoints to authorized users only.
  • Disable the basic-auth application if not required.
  • Ensure tracing and assessment endpoints are properly secured.
  • Implement role-based access control for sensitive data.
  • Apply vendor patches when available.
