Vulnerability Title
In aiohttp, compressed files as symlinks are not protected from path traversal
Vulnerability Description
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions on the 3.10 branch prior to version 3.10.2, static routes which contain files with compressed variants (`.gz` or `.br` extension) are vulnerable to path traversal outside the root directory if those variants are symbolic links. The server protects static routes from path traversal outside the root directory when `follow_symlinks=False` (default). It does this by resolving the requested URL to an absolute path and then checking that path relative to the root. However, these checks are not performed when looking for compressed variants in the `FileResponse` class, and symbolic links are then automatically followed when performing the `Path.stat()` and `Path.open()` to send the file. Version 3.10.2 contains a patch for the issue.

Vulnerability Title
aiohttp 安全漏洞
Vulnerability Description
aiohttp是aio-libs开源的一个开源的用于 asyncio 和 Python 的异步 HTTP 客户端/服务器框架。 aiohttp 3.10.2之前版本存在安全漏洞，该漏洞源于FileResponse类在查找压缩文件变体时没有执行与根目录相对的路径检查，并且符号链接在执行Path.stat和Path.open发送文件时会自动跟随，导致容易受到路径遍历攻击。
