python3-aiohttp: aiohttp is an asynchronous HTTP client/server framework for asyncio and Python
CVE-2021-21330 is fixed in python3-aiohttp on 1 platform, first by python3-aiohttp 3.0.1-1ubuntu0.1~esm1, released February 25, 2021. It is not reported as exploited. Patch Radar priority: Routine.
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 your applications.
