The framework calls torch.load() on model weight files such as llm.pt, flow.pt and hift.pt without weights_only=True, so arbitrary Python objects can be deserialized through the pickle module. When a victim starts the CosyVoice Web UI pointing at a malicious model directory, arbitrary code runs on their system during model loading.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-31252","publishedAt":"2026-05-11T17:16:20.187Z","cveId":"CVE-2026-31252","cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["CosyVoice"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"CosyVoice insecure deserialization in model loading via torch.load","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00112,"epssCheckedAt":"2026-11-07T12:08:48.660Z","kevDateAdded":null,"advisoryAliases":["GHSA-4xxc-9mf8-p66h"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-03T06:12:06.280Z","patchAvailable":null,"disclosureDate":"2026-05-11T17:16:20.187Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[]}}
