GHSA-v6wp-4m6f-gcjg `aiohttp` Open Redirect vulnerability (`normalize_path_middleware` middleware)

• PyPI aiohttp: < 3.7.4 → fixed in 3.7.4

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.
