CVE-2024-37060Public exploitNetwork attack vector

Code execution via unsafe Recipe pickle loading

Published Jun 4, 2024 · Updated Aug 2, 2024

Deserialization in MLflow Recipes 1.27.0 and later allows remote attackers to execute arbitrary code through a crafted Recipe. BaseCard.load deserializes a Recipe-supplied pickle file without validating its contents. Execution requires a user to obtain the attacker's Recipe and run mlflow run against its directory; payload code then runs with that user's privileges.
