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-2026-63732 9router before 0.4.60 Remote Code Execution via default password

9router 0.4.59 fixed in 0.4.60 contains a chain of vulnerabilities: a hardcoded default password 123456 that authenticates any fresh installation, a bypass of the LOCALONLY network gate via a spoofed Host header, and unvalidated arguments passed to childprocess.spawn when registering MCP plugins....

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...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Overview 9router is a 9Router CLI - Start and manage 9Router server Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the PATCH /api/settings endpoint, which writes the entire request body to persistent settings...

Command Injection

Overview 9router is a 9Router CLI - Start and manage 9Router server Affected versions of this package are vulnerable to Command Injection via unvalidated arguments passed to the childprocess.spawn function. An attacker can execute arbitrary commands on the host operating system by sending malicio...

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-2026-56678

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-2026-49353

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: 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-2026-56678

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-2026-56679 9Router: Mass assignment in PATCH /api/settings allows authenticated authorization downgrade

9Router is an AI router & token saver. Prior to 0.5.4, the PATCH /api/settings endpoint writes the entire request body to persistent settings without a field whitelist, allowing an authenticated user to set security-critical fields such as requireLogin and disable authentication for the whole...

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...
