{"id":"CVE-2024-1558","aliases":["BIT-mlflow-2024-1558","GHSA-j62r-wxqq-f3gf","PYSEC-2026-1653"],"url":"https://o3.security/vulnerability/CVE-2024-1558","summary":"Path Traversal Vulnerability in mlflow/mlflow","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.","published":"2024-04-16T00:00:14.626Z","modified":"2026-08-07T21:09:08.068237Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"mlflow","fixedVersion":"2.12.1"}],"fix":null,"references":[{"type":"WEB","url":"https://huntr.com/bounties/7f4dbcc5-b6b3-43dd-b310-e2d0556a8081"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/1xxx/CVE-2024-1558.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-1558"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T21:09:08.068237Z"}}
