aiohttp is an asynchronous HTTP client/server framework for asyncio and
Python. A XSS vulnerability exists on index pages for static file handling.
This vulnerability is fixed in 3.9.4. We have always recommended using a
reverse proxy server (e.g. nginx) for serving static files. Users following
the recommendation are unaffected. Other users can disable show_index if
unable to upgrade.
