A malicious user could use this issue to access internal HTTP(s) servers and in the worst case (ie: aws instance) it could be abused to get a remote code execution on the victim machine.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| mlflow | < 2.9.2 |
2.9.2 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
mlflow PyPI → 2.9.2
- pip
pip install --upgrade "mlflow>=2.9.2"- poetry
poetry add "mlflow>=2.9.2"- uv
uv add "mlflow>=2.9.2"
