We at Tachyon found an auth bypass in MLflow https://tachyon.so/blog/cve-2025-14297-mlflow-authorization-bypass: 1. Black-box scanners would need to discover the right users, roles, and state transitions, then generate specific request sequences that trigger a gap: a combinatorial problem that...

MLflow < 3.8.0 Authentication Bypass (ZDI-26-111)

The version of MLflow installed on the remote host is prior to 3.8.0. It is, therefore, affected by an authentication bypass vulnerability: - A use of default password vulnerability exists in the basicauth.ini file. The file contains hard-coded default credentials that allow remote, unauthenticat...

CVE-2026-2033

A flaw was found in MLflow Tracking Server. A remote attacker can exploit a directory traversal vulnerability by providing a specially crafted artifact file path. This issue, caused by a lack of proper validation of user-supplied paths, allows the attacker to execute arbitrary code in the context...

CVE-2026-2635

A flaw was found in MLflow. A remote attacker can exploit this vulnerability by leveraging hard-coded default credentials present in the basicauth.ini file. This allows the attacker to bypass authentication and execute arbitrary code in the context of the mlflow python application. Mitigation...
