{"cve":"CVE-2026-3198","nvd":{"published":"2026-06-02T04:17:03.397","modified":"2026-07-21T19:10:00.107","status":"Analyzed","description":"MLflow 3.9.0 with basic-auth (`--app-name basic-auth`) fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the `BEFORE_REQUEST_HANDLERS` dictionary in `mlflow/server/auth/__init__.py` does not include entries for `ListGatewaySecretInfos`, `ListGatewayEndpoints`, and `ListGatewayModelDefinitions`. This allows any authenticated user, regardless of their assigned permissions, to enumerate all gateway secrets, endpoints, and model definitions. This vulnerability exposes sensitive information, such as API keys, endpoint configurations, and proprietary model definitions, to unauthorized users.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-284"],"references":["https://huntr.com/bounties/e57db731-97d3-40c3-a429-831ee959807f","https://huntr.com/bounties/e57db731-97d3-40c3-a429-831ee959807f"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-3198","score":0.00244,"percentile":0.15624,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r5m9-wm49-959f","url":"https://osv.dev/vulnerability/GHSA-r5m9-wm49-959f","summary":"MLflow: Any authenticated user can enumerate all gateway secrets, endpoints, and model definitions","modified":"2026-07-13T16:42:37.733340178Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<3.11.0rc0"],"fixed":["3.11.0rc0"]}]},{"id":"PYSEC-2026-2659","url":"https://osv.dev/vulnerability/PYSEC-2026-2659","summary":"MLflow: Any authenticated user can enumerate all gateway secrets, endpoints, and model definitions","modified":"2026-07-13T16:42:37.733340178Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<3.11.0rc0"],"fixed":["3.11.0rc0"]}]}],"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).
