The vulnerability in 9Router affects the local-only access gate in the src/dashboardGuard.js file, which improperly uses Host and Origin headers for access control. This flaw allows attackers to spoof headers in reverse proxy or tunnel configurations, potentially exposing sensitive API endpoints to unauthorized access. Organizations using versions 0.4.45 and earlier should prioritize patching this vulnerability to mitigate the risk of exploitation.

Original NVD Description

9Router is an AI router & token saver. In 0.4.45 and earlier, 9Router's src/dashboardGuard.js local-only access gate used Host and Origin headers in isLocalRequest() to protect /api/mcp/*, /api/tunnel/*, and /api/cli-tools/*, allowing header spoofing in reverse proxy or tunnel deployments to reach MCP child process stdin paths.
