CVE-2026-49353 · 9Router: Local-Only Access Gate Bypass in 9router via Host Header SpoofING
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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.
