| summary: Request smuggling due to improper request handling in golang.org/x/net/http2/h2c |
| description: |- |
| A request smuggling attack is possible when using MaxBytesHandler. |
| |
| When using MaxBytesHandler, the body of an HTTP request is not fully consumed. |
| When the server attempts to read HTTP2 frames from the connection, it will |
| instead be reading the body of the HTTP request, which could be |
| attacker-manipulated to represent arbitrary HTTP2 requests. |
