      "value": "Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. Prior to 1.4.0, the pipecat development runner registers a /ws WebSocket endpoint for telephony testing that accepts connections without authentication, reads an attacker-supplied callSid from a Twilio stream-start handshake in src/pipecat/runner/utils.py, and passes it to TwilioFrameSerializer so the server can issue an authenticated Twilio REST API hang-up request with the server operator's credentials; equivalent unauthenticated call-control sinks exist for Telnyx and Plivo. This issue is fixed in version 1.4.0."

Antes de la versión 1.4.0, el ejecutor de desarrollo de pipecat registra un endpoint WebSocket /ws para pruebas de telefonía que acepta conexiones sin autenticación, lee un callSid proporcionado por el atacante de un handshake de inicio de flujo de Twilio en src/pipecat/runner/utils.py, y lo pasa a TwilioFrameSerializer para que el servidor pueda emitir una solicitud de colgar de la API REST de Twilio autenticada con las credenciales del operador del servidor; existen sumideros de control de llamadas no autenticados equivalentes para Telnyx y Plivo. Este problema se corrige en la versión 1.4.0."
