golang.org/x/net/http2/h2c is vulnerable to HTTP Request Smuggling. The vulnerability exists in the h2cUpgrade function of h2c.go because it does not properly handle errors when reading the HTTP2 frames from the HTTP/1 request body using MaxBytesHandler, which allows an attacker to send arbitrary HTTP2 requests to the server.
