The flaw sits in the parsing of model files, where user-supplied data is not properly validated, leading to deserialization of untrusted data. A remote attacker can execute code in the context of the current user, provided the target visits a malicious page or opens a malicious file.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-14921","publishedAt":"2025-12-24T02:15:47.340Z","cveId":"CVE-2025-14921","cweIds":["CWE-502"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["Hugging Face Transformers","Transformer-XL"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Hugging Face Transformers code execution via deserialization of model files","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00329,"epssCheckedAt":"2026-11-04T06:10:14.410Z","kevDateAdded":null,"advisoryAliases":["GHSA-hv5j-58mm-f6v9"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-04T06:10:20.963Z","patchAvailable":null,"disclosureDate":null,"fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-586"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[]}}
