{"cve":"CVE-2024-1558","nvd":{"published":"2024-04-16T00:15:08.533","modified":"2026-06-17T07:04:30.073","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://huntr.com/bounties/7f4dbcc5-b6b3-43dd-b310-e2d0556a8081","https://huntr.com/bounties/7f4dbcc5-b6b3-43dd-b310-e2d0556a8081"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T21:48:32.179249784+00:00"},"epss":{"cve":"CVE-2024-1558","score":0.00859,"percentile":0.58494,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j62r-wxqq-f3gf","url":"https://osv.dev/vulnerability/GHSA-j62r-wxqq-f3gf","summary":"mlflow vulnerable to Path Traversal","modified":"2026-07-07T17:56:41.515603161Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.12.1"],"fixed":["2.12.1"]}]},{"id":"PYSEC-2026-1653","url":"https://osv.dev/vulnerability/PYSEC-2026-1653","summary":"mlflow vulnerable to Path Traversal","modified":"2026-07-07T17:56:41.515603161Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.12.1"],"fixed":["2.12.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
