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-key gate and cause the server to make upstream provider calls using operator-stored LLM provider credentials. This issue is fixed in version 0.5.2.
AnalysisAI
Authorization-gate bypass in 9Router (decolua/9router) before 0.5.2 lets a remote unauthenticated attacker reach protected upstream LLM functionality through the /codex/* path, which next.config.mjs rewrites to /api/v1/responses without ever passing through the dashboardGuard API-key check. Because src/dashboardGuard.js only allowlists /v1, /v1beta, /api/v1, and /api/v1beta — omitting /codex — attackers can force the server to make upstream provider calls billed to operator-stored LLM credentials. No public exploit identified at time of analysis; fixed in 0.5.2.
