The local API server has a CORS misconfiguration: it replaces user-configured trusted hosts with a wildcard that reflects arbitrary origins with credentials. Network-adjacent attackers, or attackers using DNS rebinding, can reach the unauthenticated OpenAI-compatible API to run inference, enumerate models, invoke MCP tools, and read cross-origin responses.","solution":"Fixed in commit 3e1c1e7.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-66005","publishedAt":"2026-07-24T15:19:07.203Z","cveId":"CVE-2026-66005","cweIds":["CWE-183","CWE-942"],"cvssScore":"6.3","cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Jan"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Jan local API server CORS misconfiguration allows trusted host bypass","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"required","exploitMaturity":"unknown","epssScore":0.00331,"epssCheckedAt":"2026-11-12T18:09:37.393Z","kevDateAdded":null,"advisoryAliases":["GHSA-4r96-7xrx-4gcr"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-09T12:11:09.415Z","patchAvailable":null,"disclosureDate":"2026-07-24T15:19:07.203Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
