Eric Christensen 2021-06-23 14:59:42 UTC Doc Text A flaw was found in python-urllib3. SSL certificate validation is omitted in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted.
