When `convert_version()` processes an Upsample node with zero inputs, the adapter reads `node->inputs()[0]` without checking the input count, causing a SIGSEGV crash on Release builds and an abort on Debug builds. Any application running `convert_version()` on untrusted models is affected, and a 107-byte proof of concept reproduces the crash on onnx 1.21.0 and 1.22.0.","solution":"The source states that a full audit of about 45 adapters found eight with the same unguarded indexed access, and that all eight, including upsample_6_7, have been fixed in PR #7813.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-hwpq-hmq9-wj77","publishedAt":"2026-07-07T13:02:10.000Z","cveId":"CVE-2026-44512","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["onnx@>= 1.9.0, < 1.22.0 (fixed: 1.22.0)"],"affectedPackageNames":["onnx"],"affectedPackageRefs":["pypi:onnx"],"affectedVendors":[],"affectedVendorsRaw":["ONNX"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00193,"epssCheckedAt":"2026-10-14T12:12:42.415Z","kevDateAdded":null,"advisoryAliases":["GHSA-hwpq-hmq9-wj77"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-07-07T13:02:10.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
