The remote host is affected by the vulnerability described in GLSA-202208-19 (aiohttp: Open redirect vulnerability)
aiohttp.web_middlewares.normalize_path_middleware
middleware. This security problem has been fixed in 3.7.4. Upgrade your dependency using pip as follows pip install aiohttp >= 3.7.4. If upgrading is not an option for you, a workaround can be to avoid using aiohttp.web_middlewares.normalize_path_middleware
in your applications. (CVE-2021-21330)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The remote host is affected by the vulnerability described in GLSA-202208-19 (aiohttp: Open redirect vulnerability)
- aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In aiohttp before version
3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server
could redirect the browser to a different website. It is caused by a bug in the
`aiohttp.web_middlewares.normalize_path_middleware` middleware. This security problem has been fixed in
3.7.4. Upgrade your dependency using pip as follows pip install aiohttp >= 3.7.4. If upgrading is not an
option for you, a workaround can be to avoid using `aiohttp.web_middlewares.normalize_path_middleware` in
