{"id":"BIT-mlflow-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.","aliases":["CVE-2024-1558","GHSA-j62r-wxqq-f3gf","PYSEC-2026-1653"],"modified":"2026-09-08T08:47:42.649503179Z","published":"2025-02-04T07:22:09.430Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://huntr.com/bounties/7f4dbcc5-b6b3-43dd-b310-e2d0556a8081"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-1558"}],"affected":[{"package":{"name":"mlflow","ecosystem":"Bitnami","purl":"pkg:bitnami/mlflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.12.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mlflow/BIT-mlflow-2024-1558.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
