Remote Code Execution due to Full Controled File Write in mlflow

  • Disclosed: 16.11.2023
  • Updated: 11.10.2026 14:17

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.
