Overview

A security vulnerability (CVE-2025-52967) was identified in MLflow versions prior to 3.1.0, where the gatewayproxyhandler component lacked proper gateway_path validation. The vulnerability was discovered and disclosed in June 2025, affecting all versions of MLflow before 3.1.0 (NVD, MITRE).

Technical details

The vulnerability stems from insufficient validation of the gatewaypath parameter in the gatewayproxy_handler component. It has been classified as CWE-918 (Server-Side Request Forgery). The CVSS v3.1 base score is 5.8 (Medium), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N, indicating network accessibility with low attack complexity and no privileges required (NVD, Wiz).
