CVE-2023-6018

CRITICAL

Remote Code Execution due to Full Controled File Write in mlflow

Published June 29, 2026Updated July 13, 2026Source: osv

Summary

The mlflow web server includes tools for tracking experiments, packaging code into reproducible runs, and sharing and deploying models. As this vulnerability allows to write / overwrite any file on the file system, it gives a lot of ways to archive code execution (like overwriting `/home/<user>/.bashrc`). A malicious user could use this issue to get command execution on the vulnerable machine and get access to data & models information.

Remediation

Upgrade to the fixed version using your package manager.

pip
Update mlflow to 2.9.2 or later
pip install "mlflow>=2.9.2"
