Vulnerability	Vulnerable Version
M 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.	[,3.10.11)
M UNIX Symbolic Link (Symlink) Following Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following through the `FileResponse` class due to improper validation for compressed variants. An attacker can access files outside the intended directory by manipulating symbolic links to point to restricted areas by performing `Path.stat()` and `Path.open()` to send the file. Note This vulnerability impacts servers with static routes that contain compressed variants as symbolic links pointing outside the root directory or that permit users to upload or create such links. How to fix UNIX Symbolic Link (Symlink) Following? Upgrade `aiohttp` to version 3.10.2 or higher.	[,3.10.2)
