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...
