CVE-2021-21330 – Open redirect vulnerability in aiohttp

https://notcve.org/view.php?id=CVE-2021-21330

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. • https://github.com/aio-libs/aiohttp/blob/master/CHANGES.rst#374-2021-02-25 https://github.com/aio-libs/aiohttp/commit/2545222a3853e31ace15d87ae0e2effb7da0c96b https://github.com/aio-libs/aiohttp/security/advisories/GHSA-v6wp-4m6f-gcjg https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FU7ENI54JNEK3PHEFGCE46DGMFNTVU6L https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JN3V7CZJRT4QFCVXB6LDPCJH7NAOFCA5 https://pypi.org/project/aiohttp https://secu • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
