Summary
`aiohttp` Open Redirect vulnerability (`normalize_path_middleware` middleware)
Details

Impact

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.

Patches

This security problem has been fixed in v3.7.4. Upgrade your dependency as follows: [pip install aiohttp >= 3.7.4]

Workarounds

If upgrading is not an option for you, a workaround can be to avoid using aiohttp.web_middlewares.normalize_path_middleware in your applications.
