El m\u00e9todo 'deserialize()' de la clase utiliza 'pickle.loads()' de Python en los datos recibidos de los clientes WebSocket sin ninguna validaci\u00f3n o sanitizaci\u00f3n. Esto significa que un cliente WebSocket malicioso puede enviar una carga \u00fatil pickle manipulada para ejecutar c\u00f3digo arbitrario en el servidor Pipecat. El c\u00f3digo vulnerable reside en 'src/pipecat/serializers/livekit.py' (alrededor de la l\u00ednea 73), donde los datos de mensajes WebSocket no confiables se pasan directamente a 'pickle.loads()' para la deserializaci\u00f3n. Si un servidor Pipecat est\u00e1 configurado para usar LivekitFrameSerializer y est\u00e1 escuchando en una interfaz externa (por ejemplo, 0.0.0.0), un atacante en la red (o en internet, si el servicio est\u00e1 expuesto) podr\u00eda lograr la ejecuci\u00f3n remota de c\u00f3digo (RCE) en el servidor enviando una carga \u00fatil pickle maliciosa.

La mejor mitigaci\u00f3n es dejar de usar el LivekitFrameSerializer vulnerable por completo. Aquellos que requieran la funcionalidad de LiveKit deben actualizar a la \u00faltima versi\u00f3n de Pipecat y cambiar al 'LiveKitTransport' recomendado u otro m\u00e9todo seguro proporcionado por el framework.
