Upgrade aiohttp to version 3.10.2 or higher.
Overview
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.
