Upgrade mlflow to version 2.3.0 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 Arbitrary File Read due to a bypass of the fix for CVE-2023-1177. This allows attackers to download arbitrary files unrelated to MLflow from the host server, including any files stored in remote locations to which the host server has access.
