    - Security Update to 2.31.0 (bsc#1211674):
      Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
      forwarding of Proxy-Authorization headers to destination servers when
      following HTTPS redirects.
      When proxies are defined with user info (https://user:pass@proxy:8080), Requests
      will construct a Proxy-Authorization header that is attached to the request to
      authenticate with the proxy.
      In cases where Requests receives a redirect response, it previously reattached
      the Proxy-Authorization header incorrectly, resulting in the value being
      sent through the tunneled connection to the destination server. Users who rely on
      defining their proxy credentials in the URL are strongly encouraged to upgrade
      to Requests 2.31
