The gateway proxy endpoint (mlflow/server/gateway_api.py, raw_proxy) subsequently issues an HTTP request to that stored api_base plus a caller-supplied path and returns the full response body. MLflow's existing SSRF guard, _validate_webhook_url (which blocks non-global and metadata IPs), is never invoked anywhere in this gateway secret/proxy code path. The CreateGatewaySecret action additionally has no entry in the permission-validator map, so it requires only basic authentication rather than any specific scope, meaning any authenticated user \u2014 including read-only accounts \u2014 can create a secret pointing at an internal address and reach it via the proxy endpoint, potentially exposing cloud-instance IAM credentials via metadata services. This is related to CVE-2026-4035, which addresses a distinct mechanism in the same gateway-secret feature (server-side $ENV_VAR resolution inside the api_key field leaking credentials to the configured upstream); the finding here is an independent missing-validation gap in the api_base destination itself, unaffected by that fix."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-918 Server-Side Request Forgery (SSRF)", "cweId": "CWE-918", "type": "CWE"}]}], "affected": [{"vendor": "mlflow", "product": "mlflow", "programFiles": ["mlflow/server/handlers.py", "mlflow/server/gateway_api.py"], "versions": [{"version": "0", "lessThanOrEqual": "3.14.0", "versionType": "custom", "status": "affected"}], "defaultStatus": "unknown"}], "metrics": [{"other": {"type": "CVSS_3.1_severity", "content": {"value": "HIGH"}}}, {"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N", "baseScore": 7.7, "baseSeverity": "HIGH"}}], "references": [{"url": "https://github.com/mlflow/mlflow/tree/v3.14.0/mlflow"}], "credits": [{"lang": "en", "value": "Abdivasiyev Sunnatillo", "type": "finder"}], "providerMetadata": {"orgId": "309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c", "shortName": "TuranSec", "dateUpdated": "2026-08-05T06:59:23.394Z"}}}}
