The raw_proxy endpoint in mlflow/server/gateway_api.py then sends requests to that stored address plus a caller-supplied path and returns the full response body. Because CreateGatewaySecret has no entry in the permission-validator map, any authenticated user, including read-only accounts, can exploit this, potentially exposing cloud-instance IAM credentials via metadata services. The flaw is independent of CVE-2026-4035.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-71211","publishedAt":"2026-08-05T08:16:43.367Z","cveId":"CVE-2026-71211","cweIds":["CWE-918"],"cvssScore":"7.1","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["mlflow@>= 3.13.0, <= 3.15.2"],"affectedPackageNames":["mlflow"],"affectedPackageRefs":["pypi:mlflow"],"affectedVendors":[],"affectedVendorsRaw":["MLflow AI Gateway"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"MLflow AI Gateway SSRF via unvalidated api_base in gateway secrets","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.0029,"epssCheckedAt":"2026-11-04T12:08:35.508Z","kevDateAdded":null,"advisoryAliases":["GHSA-h7x2-h6g9-p789"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:46:00.717Z","patchAvailable":null,"disclosureDate":"2026-08-05T08:16:43.367Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-664"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null,"fixes":[]}}
