It was discovered that when sending HTTP requests without using
urllib3’s proxy support, it’s possible to accidentally set the
Proxy-Authorization header even though it won’t have any effect as the
request is not using a forwarding proxy or a tunneling proxy.
In those cases, urllib3 doesn’t treat the Proxy-Authorization HTTP
header as one carrying authentication material and thus doesn’t strip
the header on cross-origin redirects, which might lead to authorization
bypass.
For Debian 10 buster, these problems have been fixed in version 1.24.1-1+deb10u3.
For Debian 8 jessie, these problems have been fixed in version 1.9.1-3+deb8u3.
For Debian 9 stretch, these problems have been fixed in version 1.19.1-1+deb9u3.
We recommend that you upgrade your python-urllib3 packages.
