  "title": "python-aiohttp: aiohttp is an asynchronous HTTP client/server framework for asyncio and Python",
  "description": "aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit \u0060d5c12ba89\u0060 which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues.",
