Arbitrary file read via DBFS source validation
Published Mar 20, 2025 · Updated Mar 20, 2025
Path traversal in MLflow before 2.17.0 allows remote attackers to read arbitrary local files through crafted DBFS model sources. The model-version source validator checks only the parsed URL path, so an encoded query delimiter can hide dot-dot segments that later enter file-URI resolution. Exposure requires a tracking server with DBFS configured and mounted to a local directory; successful requests disclose files readable by the server process.

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.
