Sensitive file disclosure via URI misclassification
Published Dec 20, 2023 · Updated Aug 2, 2024
Path traversal in MLflow before 2.9.2 allows remote attackers to read sensitive server files through the tracking server. The is_local_uri function misclassifies scheme-less network-path references as nonlocal, allowing crafted artifact paths to reach files outside the intended store. Exposure requires network access to the tracking server, and disclosure is limited to files readable by the server process; integrity and availability effects are not established.

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.
