Unauthenticated remote attackers can send a malicious model_id containing ../ sequences to POST /api/3.0/mlflow/runs/outputs, creating directories and writing a meta.yaml file at arbitrary filesystem locations, limited only by the server account's permissions. FileStore was the default backend before 3.7.0 and is opt-in afterward through MLFLOW_ALLOW_FILE_STORE.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-127202","publishedAt":"2026-11-12T17:17:43.450Z","cveId":"CVE-2026-127202","cweIds":["CWE-22"],"cvssScore":"5.3","cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["MLflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"MLflow path traversal through model_id in the log outputs API","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0,"epssCheckedAt":"2026-11-12T18:09:36.308Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-12T18:09:40.092Z","patchAvailable":null,"disclosureDate":"2026-11-12T17:17:43.450Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-126"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
