Package        : python-aiohttp
CVE ID         : CVE-2021-21330

Beast Glatisant and Jelmer Vernooij reported that python-aiohttp, a
async HTTP client/server framework, is prone to an open redirect
vulnerability. A maliciously crafted link to an aiohttp-based web-server
could redirect the browser to a different website.

For the stable distribution (buster), this problem has been fixed in
version 3.5.1-1+deb10u1.

We recommend that you upgrade your python-aiohttp packages.

For the detailed security status of python-aiohttp please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/python-aiohttp
