An unauthenticated attacker can submit a crafted trace ID with traversal sequences to POST /api/3.0/mlflow/traces, causing FileStore.start_trace() to write trace_info.yaml, request_metadata and tag files outside the intended experiment trace directory, limited by the server process's filesystem permissions. FileStore is the default backend before MLflow 3.7.0 and opt-in afterward, so earlier deployments are exposed by default while later ones are exposed only when FileStore is explicitly selected.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53995","publishedAt":"2026-10-19T22:17:11.013Z","cveId":"CVE-2026-53995","cweIds":["CWE-22"],"cvssScore":"8.2","cvssSeverity":"high","severity":"high","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 in FileStore trace writes via POST /api/3.0/mlflow/traces","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0,"epssCheckedAt":"2026-10-20T06:15:30.055Z","kevDateAdded":null,"advisoryAliases":["GHSA-wqmh-qccw-pqwf"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-20T06:15:35.461Z","patchAvailable":null,"disclosureDate":"2026-10-19T22:17:11.013Z","capecIds":["CAPEC-126"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
