aiohttp is vulnerable to HTTP Request Smuggling. The vulnerability occurs due to the use of vulnerable llhttp
component. When a specially constructed HTTP request is submitted, it leads to HTTP request smuggling because the server interprets one of the HTTP header values incorrectly. Only aiohttp’s HTTP server (aiohttp.Application) is impacted.
