aiohttp is vulnerable to HTTP Request Smuggling. The vulnerability exists due to various issues with header parsing in http_parser.py. This allows a remote attacker to smuggle an HTTP request by submitting a maliciously crafted header. This is impactful when AIOHTTP_NO_EXTENSIONS is enabled or when not using a prebuilt wheel.
