CVE-2023-49081

aiohttp is an asynchronous HTTP client/server framework for asyncio and
Python. Improper validation made it possible for an attacker to modify the
HTTP request (e.g. to insert a new header) or create a new HTTP request if
the attacker controls the HTTP version. The vulnerability only occurs if
the attacker can control the HTTP version of the request. This issue has
been patched in version 3.9.0.
