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.
