NVD description
MLflow is an open source AI engineering platform for agents, large language models, and machine learning models. From 3.13.0 until 3.15.0, LogInputs is absent from BEFORE_REQUEST_HANDLERS in the mlflow/server/auth package, allowing any authenticated user to call POST /api/2.0/mlflow/runs/log-inputs for another user's run_id and inject attacker-controlled DatasetInput records into the dataset_inputs lineage metadata without UPDATE permission. This issue is fixed in version 3.15.0.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep MLflow off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
