CVE-2024-2928Network attack vector

Arbitrary file read via unvalidated URI fragments

Published Jun 6, 2024 · Updated Aug 1, 2024

Path traversal in MLflow before 2.11.3 allows remote attackers to read arbitrary server files through crafted artifact-location URIs. The _create_experiment handler accepted artifact_location URLs containing fragments while validating only query strings, allowing traversal sequences to reach local file resolution. An unauthenticated network request to an exposed tracking server is sufficient, and access is limited to files readable by the server process.
