HTTP Request Smuggling

Affected versions of this package are vulnerable to HTTP Request Smuggling due to incorrect parsing of newlines in chunk extensions via the feed_data function. An attacker can bypass firewall or proxy protections by sending specially crafted requests.

Note:

Exploiting this vulnerability is possible when a pure Python version of aiohttp is installed (Without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled.

How to fix HTTP Request Smuggling?

Upgrade aiohttp to version 3.10.11 or higher.
