NVD Description

Note: Versions mentioned in the description apply only to the upstream nemo package and not the nemo package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. 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.
