9Router <= 0.4.36 - Unauthenticated RCE

9Router = 0.4.36 middleware only guards 8 explicitly listed routes, leaving /api/cli-tools/ and /api/mcp/ entirely unauthenticated. An attacker can POST to /api/cli-tools/cowork-settings to register a custom MCP plugin with attacker-controlled command and args stored verbatim into globalThis, the...

CVE-2026-63313

9Router before 0.4.72 is affected by a server-side request forgery (SSRF) in the /v1/web/fetch endpoint. The endpoint accepts a user-supplied url and passes it to an external scraping provider (Firecrawl, Jina Reader, Tavily, or Exa). Validation only checks syntactic correctness via new URL(), wi...

CVE-2026-56678

9Router is an AI router & token saver. Prior to 0.5.6, the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key builds an upstream URL using a user-controlled region value, allowing an authenticated attacker to supply a crafted region such as kiro-canary.local:8443 and cause 9Router to...

CVE-2026-62312

9Router is an AI router & token saver. Prior to 0.5.2, 9Router allows a remote authenticated attacker to achieve arbitrary code execution on the host operating system by combining a Host header bypass of localhost-only routes with unvalidated MCP plugin args passed to childprocess.spawn, allowing...

CVE-2026-49353

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...

CVE-2026-46339

9Router is an AI router & token saver. From 0.4.30 until 0.4.37, 9Router's src/proxy.js middleware did not protect /api/cli-tools/ and /api/mcp/, allowing unauthenticated registration of customPlugins through src/app/api/cli-tools/cowork-settings/route.js and command execution through the MCP...

CVE-2026-62312

CVE-2026-62312 affects 9Router, an AI router & token saver. Before v0.5.2, an authenticated remote attacker can achieve arbitrary code execution on the host by abusing a Host header bypass of localhost-only routes in combination with unvalidated MCP plugin arguments passed to child_process.spawn(...

CVE-2026-56678

9Router prior to v0.5.6 is vulnerable in the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key, which builds an upstream URL from a user-controlled region value. An authenticated attacker can supply a crafted region (example: kiro-canary.local:8443#) to trigger SSRF by directing the v...

CVE-2026-56678 9Router: Kiro region injection allows authenticated SSRF with Authorization header forwarding

9Router is an AI router & token saver. Prior to 0.5.6, the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key builds an upstream URL using a user-controlled region value, allowing an authenticated attacker to supply a crafted region such as kiro-canary.local:8443 and cause 9Router to...

CVE-2026-49353 9Router: Local-Only Access Gate Bypass in 9router via Host Header SpoofING

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...

CVE-2026-49353

Summary (CVE-2026-49353): 9Router before 0.4.46 has a local‑only access gate in src/dashboardGuard.js that relies on Host and Origin headers to classify requests as local. In proxied/tunneled deployments (reverse proxy, Cloudflare Tunnel, Tailscale), these headers are attacker‑controlled, enablin...

CVE-2026-49353 9Router: Local-Only Access Gate Bypass in 9router via Host Header SpoofING

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...

CVE-2026-49352

CVE-2026-49352 affects 9router, a Node.js/Next.js AI router. The vulnerability stems from a hardcoded fallback JWT secret, implemented as the public string 9router-default-secret-change-me, used when JWT_SECRET is unset in multiple files. An attacker can forge a valid auth_token cookie and gain a...

CVE-2026-49352 9Router: Hardcoded Default fallback JWT Secret Allows Authentication Bypass

9Router is an AI router & token saver. From 0.2.21 until 0.4.44, 9Router used the hardcoded fallback JWT secret 9router-default-secret-change-me in src/app/api/auth/login/route.js, src/middleware.js, and later src/lib/auth/dashboardSession.js, allowing attackers to forge an authtoken cookie when...
