Prior to 10.5.1, the Address6 isLinkLocal method in src/ipv6.ts recognizes only fe80::/64 instead of the complete fe80::/10 IPv6 link-local range. An attacker-controlled address elsewhere in fe80::/10 can therefore pass a trust-boundary check that relies on isLinkLocal. The same address is identified as link-local by getType and getScope, exposing the inconsistent classification. A successful bypass can reach an on-link host outside the intended trust boundary. This issue is fixed in version 10.5.1.","state":0,"publishedAt":"2026-09-28T18:17:21.237+00:00","modifiedAt":"2026-09-30T19:57:08.043+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/beaugunderson/ip-address/commit/d03e960c7cc3179ef25c8a44b4f94dd499625546","https://github.com/beaugunderson/ip-address/releases/tag/v10.5.1","https://github.com/beaugunderson/ip-address/security/advisories/GHSA-rpw4-54j3-4h4q"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-101913","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-697","CWE-918"],"productCriteria":[],"sourceDates":{"published":"2026-09-28T18:17:21.237","lastModified":"2026-09-30T19:57:08.043"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
