Description
Summary
The pure Python parser is vulnerable to an HTTP request smuggling attack.
Impact
If users are using the Python parser (AIOHTTP_NO_EXTENSIONS, or not a standard wheel installed), then an application may be vulnerable to a request smuggling attack.
Workaround
Switch to the default C parser.
NVD description
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the pure Python parser accepts ambiguous HTTP request framing. An unauthenticated attacker can consequently smuggle requests when an application uses AIOHTTP_NO_EXTENSIONS or otherwise runs without a standard wheel and an intermediary interprets the framing differently. This issue is fixed in version 3.14.4.
