Hi,

The following vulnerability was published for python-aiohttp.

CVE-2024-23334[0]:
| aiohttp is an asynchronous HTTP client/server framework for asyncio
| and Python. When using aiohttp as a web server and configuring
| static routes, it is necessary to specify the root path for static
| files. Additionally, the option 'follow_symlinks' can be used to
| determine whether to follow symbolic links outside the static root
| directory. When 'follow_symlinks' is set to True, there is no
| validation to check if reading a file is within the root directory.
| This can lead to directory traversal vulnerabilities, resulting in
| unauthorized access to arbitrary files on the system, even when
| symlinks are not present.  Disabling follow_symlinks and using a
| reverse proxy are encouraged mitigations.  Version 3.9.2 fixes this
| issue.
