CVE-2025-47912
Public on 2025-10-13
Modified on 2025-11-01
Description
net/url: insufficient validation of bracketed IPv6 hostnames
The Parse function permitted 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.
