BREW-airshare-CVE-2021-21330 — `aiohttp` Open Redirect vulnerability (`normalize_path_middleware` middleware)

Affected: Homebrew: airshare

### 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.
