{"id":"DEBIAN-CVE-2026-101913","details":"ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. 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.","modified":"2026-09-29T05:00:09.197695774Z","published":"2026-09-28T18:17:21.237Z","upstream":["CVE-2026-101913"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-101913"}],"affected":[{"package":{"name":"node-ip-address","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-ip-address?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.2.0-1","10.2.0-2","10.3.1-1","10.4.0-1","10.7.2-1","8.1.0-2","8.1.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-101913.json"}},{"package":{"name":"node-ip-address","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-ip-address?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.2.0-1","10.2.0-2","10.3.1-1","10.4.0-1","10.7.2-1","8.1.0-2","8.1.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-101913.json"}},{"package":{"name":"node-ip-address","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-ip-address?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.7.2-1"}]}],"versions":["10.2.0-1","10.2.0-2","10.3.1-1","10.4.0-1","8.1.0-2","8.1.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-101913.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
