Upgrade bRPC to version 1.8.0, which fixes this issue. Download link:  https://github.com/apache/brpc/releases/tag/1.8.0\n 2.

Descripción de la causa de la vulnerabilidad: http_parser no cumple con la especificación RFC-7230 HTTP 1.1. Escenario de ataque: si se recibe un mensaje con un campo de encabezado Transfer-Encoding y Content-Length, dicho mensaje podría indicar un intento de realizar contrabando de solicitudes o división de respuestas. Un escenario de ataque particular es que un bRPC creó un servidor http en el backend que recibe solicitudes en una conexión persistente desde el servidor frontend que usa TE para analizar la solicitud con la lógica de que el \"fragmento\" está contenido en el campo TE. En ese caso, un atacante puede introducir de contrabando una solicitud en la conexión con el servidor backend. Solución: Puede elegir una de las siguientes soluciones: 1. Actualice bRPC a la versión 1.8.0, que soluciona este problema. Enlace de descarga: https://github.com/apache/brpc/releases/tag/1.8.0 2.
