Prior to 4.12.21, the ip-restriction middleware (hono/ip-restriction) compares incoming IP addresses against configured deny and allow rules using string equality after partial normalization. Non-canonical IPv6 representations of an address already listed in a static rule — such as compressed forms, explicit-zero forms, or hex-notation IPv4-mapped addresses — do not match the normalized rule entry, causing the rule to be silently skipped. This vulnerability is fixed in 4.12.21.","state":0,"publishedAt":"2026-05-28T17:16:32.383+00:00","modifiedAt":"2026-10-14T20:10:00.19+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/honojs/hono/security/advisories/GHSA-xrhx-7g5j-rcj5"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47674","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-185","CWE-1289"],"productCriteria":["cpe:2.3:a:hono:hono:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-28T17:16:32.383","lastModified":"2026-10-14T20:10:00.190"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
