The script loads epoch_*.pt PyTorch checkpoints with torch.load() without weights_only=True, allowing arbitrary Python objects to be deserialized via pickle. An attacker who supplies a malicious checkpoint in a directory gains code execution on the victim's system when the victim averages models from that directory.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-31250","publishedAt":"2026-05-11T17:16:19.950Z","cveId":"CVE-2026-31250","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 average_model.py checkpoint loading","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00222,"epssCheckedAt":"2026-11-07T18:08:33.276Z","kevDateAdded":null,"advisoryAliases":["GHSA-jf74-gj4g-6qpg"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-03T06:12:07.282Z","patchAvailable":null,"disclosureDate":"2026-05-11T17:16:19.950Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[]}}
