Upgrade mlflow to version 3.13.0rc0 or higher.
Overview
mlflow is a platform to streamline machine learning development, including tracking experiments, packaging code into reproducible runs, and sharing and deploying models.
Affected versions of this package are vulnerable to Use of Default Credentials in the basic_auth.ini file. An attacker can gain unauthorized administrative access and execute arbitrary code if the default admin credentials have not been changed.
Note:
The patch in version 3.13.0rc0 does not modify the default behaviour of create_app but adds a user warning to allow user change the admin password early on.
