      "value": "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 local. A remote unauthenticated attacker can access /v1 APIs such as /v1/models and may abuse configured upstream provider credentials through /v1 proxy endpoints depending on enabled providers. This issue is fixed in version 0.5.2."

      "value": "9Router es un router de IA y un ahorrador de tokens. Antes de la versión 0.5.2, 9router trata las solicitudes de bucle invertido como de confianza y permite el acceso a /v1/* sin una clave API, por lo que un proxy inverso en el mismo host que reenvía el tráfico público al backend a través de 127.0.0.1 hace que src/dashboardGuard.js clasifique erróneamente las solicitudes externas como locales. Un atacante remoto no autenticado puede acceder a las API /v1, como /v1/models, y puede abusar de las credenciales de proveedores ascendentes configurados a través de los puntos finales de proxy /v1, dependiendo de los proveedores habilitados. Este problema está solucionado en la versión 0.5.2."
