CVE-2026-55638

9Router is an AI router & token saver. Prior to 0.5.2, 9router protects /v1, /v1beta, /api/v1, and /api/v1beta in src/dashboardGuard.js but omits /codex before next.config.mjs rewrites /codex/ to /api/v1/responses. A remote unauthenticated attacker can send requests to /codex/ to bypass the API-k...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview 9router is a 9Router CLI - Start and manage 9Router server Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition through the image process in open-sse/translator/concerns/image.js. An attacker can access internal-only HTTP services by...

CVE-2026-56675 9router: Reverse proxy locality collapse allows unauthenticated access to 9router /v1 APIs

9Router is an AI router & token saver. Prior to 0.5.2, 9router treats loopback requests as trusted and allows /v1/ access without an API key, so a same-host reverse proxy that forwards public traffic to the backend through 127.0.0.1 causes src/dashboardGuard.js to misclassify external requests as...

CVE-2026-56675

9router prior to version 0.5.2 validates loopback requests as trusted, allowing unauthenticated access to /v1/* endpoints when a reverse proxy on localhost (127.0.0.1) forwards traffic. A remote attacker could reach /v1 APIs (e.g., /v1/models) without an API key, potentially abusing configured up...

CVE-2026-55638 9router: Unauthenticated LLM proxy access via /codex rewrite authorization bypass

9Router is an AI router & token saver. Prior to 0.5.2, 9router protects /v1, /v1beta, /api/v1, and /api/v1beta in src/dashboardGuard.js but omits /codex before next.config.mjs rewrites /codex/ to /api/v1/responses. A remote unauthenticated attacker can send requests to /codex/ to bypass the API-k...

CVE-2026-55641 9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

9Router is an AI router & token saver. Prior to 0.5.2, 9router determines whether a /v1 LLM proxy request is local by reading the client-controlled Host header, allowing a remote unauthenticated attacker to send Host: localhost and bypass API-key authentication. In the default configuration, this...

CVE-2026-55500

CVE-2026-55500 (9router) exposes a critical flaw in the /api/settings/database endpoint. The GET export returns the entire database, including plaintext API keys, OAuth tokens, and provider credentials, while POST can wipe-and-replace the database with attacker-controlled data. This bypasses auth...

CVE-2026-55500 9router: Exposure of Sensitive Information and Unprotected Database Import/Export Allows Complete Credential Theft and Database Takeover

9Router is an AI router & token saver. Prior to 0.4.80, the /api/settings/database endpoint allows full database export containing all credentials, API keys, OAuth tokens, and settings and full database import complete overwrite without any authentication requirement beyond the ALWAYSPROTECTED...

CVE-2026-55501 9router: Login brute-force protection bypass via spoofed X-Forwarded-For header

9Router is an AI router & token saver. Prior to 0.4.80, the dashboard login rate limiter in src/lib/auth/loginLimiter.js derives the client identity from the attacker-controlled X-Forwarded-For HTTP header, and src/app/api/auth/login/route.js uses that spoofable value for checkLock and recordFail...
