"NIST reports: (by search in the range 2018/01/01 - 2019/11/10) :

urllib3 before version 1.23 does not remove the Authorization HTTP
header when following a cross-origin redirect (i.e., a redirect that
differs in host, port, or scheme). This can allow for credentials in
the Authorization header to be exposed to unintended hosts or
transmitted in cleartext.

In the urllib3 library through 1.24.1 for Python, CRLF injection is
possible if the attacker controls the request parameter.

The urllib3 library before 1.24.2 for Python mishandles certain cases
where the desired set of CA certificates is different from the OS
store of CA certificates, which results in SSL connections succeeding
in situations where a verification failure is the correct outcome.
This is related to use of the ssl_context, ca_certs, or ca_certs_dir
argument.");
