9Router has an Authentication Bypass in Public LLM API via Spoofable X-9r-Real-Ip Header

Summary 9router determines whether an incoming request originates from localhost by trusting the X-9r-Real-Ip HTTP request header. This header is intended to be produced and sanitized exclusively by the bundled custom-server.js layer from the TCP socket address. In deployment modes where requests...

CVE-2026-56681

9Router is an AI router & token saver. Prior to 0.5.6, 9Router deployments that allow requests to reach Next.js without the sanitizing custom-server.js wrapper trust the client-supplied X-9r-Real-Ip header in src/dashboardGuard.js when isLocalRequest decides whether canAccessPublicLlmApi may skip...

CVE-2026-56682 9Router: Login Brute-Force Lockout Bypass via Spoofable X-9r-Real-Ip Header

9Router is an AI router & token saver. Prior to 0.5.6, 9Router deployments that allow requests to reach Next.js without the sanitizing custom-server.js wrapper use the client-supplied X-9r-Real-Ip value as the bucket key in getClientIp, checkLock, and recordFail in src/lib/auth/loginLimiter.js fo...

CVE-2026-56682

9Router versions prior to 0.5.6 are vulnerable to a login brute-force lockout bypass. The application's rate-limiting mechanism, specifically in src/lib/auth/loginLimiter.js, uses the client-supplied X-9r-Real-Ip header as the bucket key for tracking failed login attempts. When deployed without t...

GHSA-86M2-FCXQ-5Q7C 9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

Summary 9router's request guard decides a request is "local" and therefore exempt from API-key auth on the /v1 LLM proxy by reading the client-controlled Host header. Because 9router binds 0.0.0.0 by default and the CLI misleadingly prints "localhost", a remote, unauthenticated attacker who can...
