A crafted tar.gz file containing `..` or absolute paths can escape the intended extraction directory, enabling arbitrary file writes. The issue affects the latest version of MLflow and is rated high/critical in multi-tenant environments or where untrusted artifacts are ingested, with potential remote code execution.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-15031","publishedAt":"2026-03-18T23:17:28.693Z","cveId":"CVE-2025-15031","cweIds":["CWE-22"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["mlflow@< 3.9.0rc0 (fixed: 3.9.0rc0)"],"affectedPackageNames":["mlflow"],"affectedPackageRefs":["pypi:mlflow"],"affectedVendors":[],"affectedVendorsRaw":["MLflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"MLflow arbitrary file write during pyfunc extraction via tar archive entries","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00893,"epssCheckedAt":"2026-11-04T12:08:34.077Z","kevDateAdded":null,"advisoryAliases":["GHSA-fhff-qmm8-h2fp"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:50:24.867Z","patchAvailable":true,"disclosureDate":"2026-03-18T23:17:28.693Z","fixReleasedAt":"2026-01-16T03:31:24.424Z","daysToFix":-61,"fixCheckedAt":"2026-10-29T21:39:47.909Z","capecIds":["CAPEC-126"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"mlflow","fixedVersion":"3.9.0rc0","matchedVersion":"3.9.0rc0","fixReleasedAt":"2026-01-16T03:31:24.424Z","daysToFix":-61,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:39:47.763Z"}]}}
