Unauthenticated code execution via unvalidated model source
Published Oct 29, 2025 · Updated Oct 29, 2025
Path traversal in MLflow Tracking Server 2.21.3 allows remote attackers to execute arbitrary code through model creation requests. The /mlflow/model-versions/create handler accepts the source field without validation and passes the supplied path into model file operations outside the intended location. No authentication is required, and successful exploitation runs code with the service account's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
