node-ip-address: ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript
CVE-2026-101910 is fixed in node-ip-address on 1 platform by DEBIAN-CVE-2026-101910 (version 10.7.2-1), released September 29, 2026. It is not reported as exploited. Patch Radar priority: Routine.
ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.2.0 until 10.5.1, the Address6 isPrivate classifier in src/ipv6.ts does not recognize the NAT64 local-use range 64:ff9b:1::/48. Applications that combine isPrivate, isLoopback, and isLinkLocal for a trust-boundary decision can treat an internal IPv4 destination encoded through that range as external. Exploitation depends on a server network using an operator-selected NAT64 prefix within the local-use range. A successful bypass can cross the intended network trust boundary. This issue is fixed in version 10.5.1.
