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.

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.
