CVE-2026-25679 is an input-validation vulnerability in the Go standard library's net/url package. The url.Parse function insufficiently validates the URL host/authority component, including IPv6 host literals, and accepts certain invalid URLs. Applications that rely on successful parsing as proof of valid host or authority syntax may consequently accept malformed input and undermine security-sensitive URL-validation logic.
