{"cve":"CVE-2026-2614","nvd":{"published":"2026-05-11T20:25:41.423","modified":"2026-08-28T16:17:23.703","status":"Modified","description":"A vulnerability in the `_create_model_version()` handler of `mlflow/server/handlers.py` in mlflow/mlflow versions 3.9.0 and earlier allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem. The issue arises when a `CreateModelVersion` request includes the tag `mlflow.prompt.is_prompt`, which bypasses source path validation. This enables an attacker to store an arbitrary local filesystem path as the model version source. The `get_model_version_artifact_handler()` function later uses this source to serve files without verifying the model version's prompt status, leading to a complete confidentiality compromise. This issue is fixed in version 3.10.0.","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://github.com/mlflow/mlflow/commit/6e801f4259d96804c73107315b24cef0f6aa115a","https://huntr.com/bounties/19380271-3fbf-4beb-987e-6fd7069c55e6","https://access.redhat.com/errata/RHSA-2026:34456","https://access.redhat.com/errata/RHSA-2026:37275","https://access.redhat.com/errata/RHSA-2026:60520"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-2614","score":0.03691,"percentile":0.89708,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-42h5-h8qh-vv9v","url":"https://osv.dev/vulnerability/GHSA-42h5-h8qh-vv9v","summary":"MLflow allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem","modified":"2026-07-13T16:42:45.636199436Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<3.10.0"],"fixed":["3.10.0"]}]},{"id":"PYSEC-2026-2654","url":"https://osv.dev/vulnerability/PYSEC-2026-2654","summary":"MLflow allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem","modified":"2026-07-13T16:42:45.636199436Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<3.10.0"],"fixed":["3.10.0"]}]}],"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).
