  - The Parse function permits values other than IPv6 addresses to be included in square brackets within the
    host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component,
    enclosed within square brackets. For example: http://[::1]/. IPv4 addresses and hostnames must not
    appear within square brackets. Parse did not enforce this requirement. (CVE-2025-47912)
