This is an incorrect implementation of the TLS 1.3 client state machine. This allows attackers in a privileged network position to completely impersonate any TLS 1.3 servers, and read or modify potentially sensitive information between clients using the wolfSSL library and these TLS servers."

Est\u00e1 es una implementaci\u00f3n incorrecta de la m\u00e1quina de estado del cliente TLS versi\u00f3n 1.3. Esto permite a atacantes en una posici\u00f3n de red privilegiada suplantar completamente cualquiera de los servidores TLS versi\u00f3n 1.3 y leer o modificar informaci\u00f3n potencialmente confidencial entre clientes que usan la biblioteca de wolfSSL y estos servidores TLS."
