This vulnerability affects all MONAI versions and cannot be overridden by users, since the code explicitly prevents the `allow_pickle` parameter from being changed.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-wg9g-w2j2-8pgr","publishedAt":"2026-08-18T20:22:42.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["model_poisoning","supply_chain"],"issueType":"vulnerability","affectedPackages":["monai@< 1.6.0 (fixed: 1.6.0)"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["MONAI","HuggingFace"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":true,"disclosureDate":"2026-08-18T20:22:42.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality","availability"],"aiComponentTargeted":"training_data","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
