Its update mechanism passes values from attacker-controlled HTTP response headers directly to filepath.Join without validation, so ../ sequences let files be written outside the update staging directory, including the Windows Startup directory. Chained with CVE-2026-42248 (Missing Signature Verification for Updates), this yields automatic, persistent code execution without user awareness. Versions 0.12.10 to 0.17.5 were tested and confirmed vulnerable; other versions were not tested.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-42249","publishedAt":"2026-04-29T12:16:19.113Z","cveId":"CVE-2026-42249","cweIds":["CWE-22","CWE-494"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Ollama"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Ollama for Windows remote code execution through update mechanism path traversal","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.01048,"epssCheckedAt":"2026-11-10T00:11:22.478Z","kevDateAdded":null,"advisoryAliases":["GHSA-7mp6-jmch-f3fh"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-03T12:11:03.098Z","patchAvailable":null,"disclosureDate":"2026-04-29T12:16:19.113Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-126"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[]}}
