Описание
Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.
A flaw was found in proxy host matching. This vulnerability allows improper bypassing of proxy settings via manipulating an IPv6 zone ID, causing unintended matches against the NO_PROXY environment variable.
