Prior to version 5.4.5, the MCP SSE server defaults to an empty secret (`process.env['NETWORK_AI_MCP_SECRET'] ?? ''` at `bin/mcp-server.ts:89`), which causes `_isAuthorized` (`lib/mcp-transport-sse.ts:254`) to return `true` unconditionally for every request — no `Authorization` header is required. Simultaneously, `_handleRequest` sets `Access-Control-Allow-Origin: *` (`lib/mcp-transport-sse.ts:272`) on every response, so a cross-origin browser fetch can read the result without restriction. An unauthenticated attacker who can lure 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. Version 5.4.5 patches the issue.","state":0,"publishedAt":"2026-07-20T16:33:43.791+00:00","modifiedAt":"2026-07-20T19:07:31.413+00:00","affected":[{"ecosystem":"Vendor product","name":"Network-AI","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Jovancoding\",\n                    \"product\": \"Network-AI\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 5.4.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L","score":7.6,"severity":"HIGH"}],"references":["https://github.com/Jovancoding/Network-AI/security/advisories/GHSA-j3vx-cx2r-pvg8","https://github.com/Jovancoding/Network-AI/commit/dc5048112283f3f4eb6c06dd2bf5aa93ef9339be","https://github.com/Jovancoding/Network-AI/releases/tag/v5.4.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-46701","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-46701","identifiers":["CVE-2026-46701"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
