SCA: security update for network-ai (GHSA-j3vx-cx2r-pvg8)

high Tenable Cloud Security Plugin ID 442270

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Network-AI is a TypeScript/Node.js multi-agent orchestrator. 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. (CVE-2026-46701)

Solution

Update the network-ai library and its related packages to version 5.4.5 or later.
