CVE-2026-69148

MLflow: CreateModelVersion source validation does not check READ permission on referenced run_id

Published Aug 17, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
MLflow is an open source AI engineering platform for agents, large language models, and machine learning models. Prior to 3.15.0, CreateModelVersion accepts a run_id or model_id after _validate_source_run() or _validate_source_model() in mlflow/server/handlers.py verifies only path containment, allowing authenticated users to create a model version that references another user's artifact directory and read files through GET /model-versions/get-artifact without the required READ permission. This issue is fixed in version 3.15.0.
