{"id":"CVE-2024-1558","details":"A path traversal vulnerability exists in the `_create_model_version()` function within `server/handlers.py` of the mlflow/mlflow repository, due to improper validation of the `source` parameter. Attackers can exploit this vulnerability by crafting a `source` parameter that bypasses the `_validate_non_local_source_contains_relative_paths(source)` function's checks, allowing for arbitrary file read access on the server. The issue arises from the handling of unquoted URL characters and the subsequent misuse of the original `source` value for model version creation, leading to the exposure of sensitive files when interacting with the `/model-versions/get-artifact` handler.","aliases":["BIT-mlflow-2024-1558","GHSA-j62r-wxqq-f3gf"],"modified":"2026-04-09T09:54:35.986939Z","published":"2024-04-16T00:15:08.533Z","references":[{"type":"REPORT","url":"https://huntr.com/bounties/7f4dbcc5-b6b3-43dd-b310-e2d0556a8081"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mlflow/mlflow","events":[{"introduced":"0"},{"fixed":"328242e01b766129396415be219cb96127097501"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.12.1"}]}}],"versions":["1.0.0","v0.2.0","v0.2.1","v0.3.0","v0.4.0","v0.4.1","v0.4.2","v0.5.0","v0.6.0","v0.7","v0.8.0","v0.8.1","v1.7.0","v2.2.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-1558.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
