      "value": "PraisonAI is a multi-agent teams system. Prior to 4.5.128, the /media-stream WebSocket endpoint in PraisonAI's call module accepts connections from any client without authentication or Twilio signature validation. Each connection opens an authenticated session to OpenAI's Realtime API using the server's API key. There are no limits on concurrent connections, message rate, or message size, allowing an unauthenticated attacker to exhaust server resources and drain the victim's OpenAI API credits. This vulnerability is fixed in 4.5.128."

      "value": "PraisonAI es un sistema de equipos multiagente. Anteriormente a la 4.5.128, el endpoint WebSocket /media-stream en el módulo de llamadas de PraisonAI acepta conexiones de cualquier cliente sin autenticación o validación de firma de Twilio. Cada conexión abre una sesión autenticada a la API en tiempo real de OpenAI utilizando la clave API del servidor. No hay límites en conexiones concurrentes, tasa de mensajes o tamaño de mensajes, permitiendo a un atacante no autenticado agotar los recursos del servidor y agotar los créditos de la API de OpenAI de la víctima. Esta vulnerabilidad se corrige en la 4.5.128."
