From 3.10.0 until 3.17.0, the prompt branch in _create_model_version() accepts schemeless relative sources because path validation runs only when a source has a URL scheme, and mlflow.prompt.is_prompt is interpreted by tag presence rather than a true value. A remote caller can store a server-local path as the model version artifact location and use /api/2.0/mlflow/model-versions/get-artifact to read files accessible to the MLflow server process. Default unauthenticated servers require no privileges, while basic-auth deployments are exposed to authenticated users who can create registered models. This issue is fixed in version 3.17.0.","state":0,"publishedAt":"2026-10-27T19:42:35.798+00:00","modifiedAt":"2026-10-28T16:13:38.096+00:00","affected":[{"ecosystem":"Vendor product","name":"mlflow","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"mlflow\",\n                    \"product\": \"mlflow\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.10.0, < 3.17.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/mlflow/mlflow/security/advisories/GHSA-m65p-9j7q-6w33","https://github.com/mlflow/mlflow/pull/25870","https://github.com/mlflow/mlflow/commit/81730a2ce4ebcd60d5d18f68c96f422ad7e30772","https://github.com/mlflow/mlflow/releases/tag/v3.17.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116690","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116690","identifiers":["CVE-2026-116690"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
