      "value": "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. A remote attacker can rotate the X-Forwarded-For value on each login attempt to receive a fresh rate-limit bucket, bypass the 5-attempt threshold and progressive lockout durations, and perform unlimited brute-force attempts against the dashboard password. This issue is fixed in version 0.4.80."

      "value": "9Router es un router de IA y ahorrador de tokens. Antes de la versión 0.4.80, el limitador de velocidad de inicio de sesión del panel de control en src/lib/auth/loginLimiter.js deriva la identidad del cliente del encabezado HTTP X-Forwarded-For controlado por el atacante, y src/app/api/auth/login/route.js utiliza ese valor falsificable para checkLock y recordFail. Un atacante remoto puede rotar el valor de X-Forwarded-For en cada intento de inicio de sesión para recibir un nuevo cubo de límite de velocidad, eludir el umbral de 5 intentos y las duraciones de bloqueo progresivas, y realizar intentos ilimitados de fuerza bruta contra la contraseña del panel de control. Este problema está solucionado en la versión 0.4.80."
