AIOHTTP is an asynchronous HTTP client/server framework for asyncio and
Python. Prior to version 3.12.14, the Python parser is vulnerable to a
request smuggling vulnerability due to not parsing trailer sections of
an HTTP request. If a pure Python version of aiohttp is installed (i.e.
without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled,
then an attacker may be able to execute a request smuggling attack to
bypass certain firewalls or proxy protections. Version 3.12.14 contains
a patch for this issue.
