| 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. |
