WS-2023-0114
Published:May 01, 2023

Users of the MLflow Open Source Project who are hosting the MLflow Model Registry using the "mlflow server" or "mlflow ui" commands using an MLflow version older than MLflow 2.3.1 may be vulnerable to a remote file access exploit if they are not limiting who can query their server (for example, by using a cloud VPC, an IP allowlist for inbound requests, or authentication / authorization middleware). This issue only affects users and integrations that run the "mlflow server" and "mlflow ui" commands. Integrations that do not make use of "mlflow server" or "mlflow ui" are unaffected; for example, the Databricks Managed MLflow product and MLflow on Azure Machine Learning do not make use of these commands and are not impacted by these vulnerabilities in any way. The vulnerability is very similar to https://nvd.nist.gov/vuln/detail/CVE-2023-1177, and a separate CVE will be published and updated here shortly.
