The FastAPI permission middleware enforces authentication only on `/gateway/` routes, leaving the Job API (`/ajax-api/3.0/jobs/*`) and the OpenTelemetry trace ingestion API (`/v1/traces`) unprotected. Unauthenticated remote attackers can submit, read, and cancel jobs and inject arbitrary trace data into experiments, because `_find_fastapi_validator()` fails to handle non-`/gateway/` paths.","solution":"Fixed in 3.10.0.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-2652","publishedAt":"2026-05-15T03:16:23.127Z","cveId":"CVE-2026-2652","cweIds":["CWE-305"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["mlflow@< 3.11.0 (fixed: 3.11.0)"],"affectedPackageNames":["mlflow"],"affectedPackageRefs":["pypi:mlflow"],"affectedVendors":[],"affectedVendorsRaw":["MLflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"mlflow authentication bypass on FastAPI routes allows unauthenticated job access","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.20783,"epssCheckedAt":"2026-11-07T06:14:04.216Z","kevDateAdded":null,"advisoryAliases":["GHSA-75cm-x2w3-8mgf"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:48:20.866Z","patchAvailable":true,"disclosureDate":"2026-05-15T03:16:23.127Z","fixReleasedAt":"2026-04-07T06:47:05.243Z","daysToFix":-38,"fixCheckedAt":"2026-10-29T21:35:59.205Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"mlflow","fixedVersion":"3.11.0","matchedVersion":"3.11.0","fixReleasedAt":"2026-04-07T06:47:05.243Z","daysToFix":-38,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:35:59.059Z"}]}}
