[release-branch.go1.21] net/http, net/http/cookiejar: avoid subdomain matches on IPv6 zones When deciding whether to forward cookies or sensitive headers across a redirect, do not attempt to interpret an IPv6 address as a domain name. Avoids a case where a maliciously-crafted redirect to an IPv6 address with a scoped addressing zone could be misinterpreted as a within-domain redirect. For example, we could interpret "::1%.www.example.com" as a subdomain of "www.example.com". Thanks to Juho Nurminen of Mattermost for reporting this issue.
