On startup, the server loads the speech synthesis model from a user-specified directory with torch.load() without weights_only=True, so pickle can deserialize arbitrary Python objects. An attacker who places malicious model files in a directory that a victim points the server to gains arbitrary code execution during server initialization.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-31251","publishedAt":"2026-05-11T17:16:20.070Z","cveId":"CVE-2026-31251","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 gRPC server model loading","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00218,"epssCheckedAt":"2026-11-07T12:08:48.810Z","kevDateAdded":null,"advisoryAliases":["GHSA-7mm4-fwjj-qfpc"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-03T06:12:06.786Z","patchAvailable":null,"disclosureDate":"2026-05-11T17:16:20.070Z","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":[]}}
