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.","state":0,"publishedAt":"2025-10-29T21:49:58+00:00","modifiedAt":"2026-05-15T10:59:24.3058212+00:00","affected":[{"ecosystem":"Go","name":"stdlib","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.24.8"},{"kind":"introduced","version":"1.25.0"},{"kind":"fixed","version":"1.25.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://go.dev/issue/75678","https://go.dev/cl/709857","https://groups.google.com/g/golang-announce/c/4Emdl2iQ_bI"],"sourceUrl":"https://osv.dev/vulnerability/GO-2025-4010","license":"OSV · upstream source license applies","key":"osv:GO-2025-4010","identifiers":["GO-2025-4010","BIT-golang-2025-47912","CVE-2025-47912"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
