''` in `bin/mcp-server.ts`), so `_isAuthorized` in `lib/mcp-transport-sse.ts` returns true for every request with no Authorization header. The server also sends `Access-Control-Allow-Origin: *` on every response, letting a cross-origin browser script read results. An attacker who lures a user to a malicious web page can invoke all 22 exposed MCP tools, including `config_set`, `agent_spawn` and `blackboard_write`, against a default-configured localhost server.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-j3vx-cx2r-pvg8","publishedAt":"2026-05-21T22:39:59.000Z","cveId":"CVE-2026-46701","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["network-ai@<= 5.4.4 (fixed: 5.4.5)"],"affectedPackageNames":["network-ai"],"affectedPackageRefs":["npm:network-ai"],"affectedVendors":[],"affectedVendorsRaw":["Network-AI","MCP (Model Context Protocol)"],"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":0.0021,"epssCheckedAt":"2026-10-14T12:12:43.798Z","kevDateAdded":null,"advisoryAliases":["GHSA-j3vx-cx2r-pvg8"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-05-21T22:39:59.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
