description = """ | ||
Vulnerable versions of hyper allow GET requests to have bodies, even if there is | ||
no Transfer-Encoding or Content-Length header. As per the HTTP 1.1 | ||
specification, such requests do not have bodies, so the body will be interpreted | ||
as a separate HTTP request. | ||
|
||
This allows an attacker who can control the body and method of an HTTP request | ||
made by hyper to inject a request with headers that would not otherwise be | ||
allowed, as demonstrated by sending a malformed HTTP request from a Substrate | ||
runtime. This allows bypassing CORS restrictions. In combination with other | ||
vulnerabilities, such as an exploitable web server listening on loopback, it may | ||
allow remote code execution. | ||
|
||
The flaw was corrected in hyper version 0.12.35. | ||
