SCA: security update for ip-address (GHSA-22jq-vg5j-6vgg)

medium Tenable Cloud Security Plugin ID 445615

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions
 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6
 addresses. Address6.getType() classifies an address by matching it against a table of known IPv6 special-
 use prefixes, returning Global unicast when nothing matches. That table had no entry for the IPv4-mapped
 range (::ffff:0:0/96), so every mapped address fell through to Global unicast; NAT64 addresses matched
 their own NAT64 … labels. The boolean checks isLoopback, isUnspecified, and isMulticast compared getType()
 against a fixed label and so returned false, while isLinkLocal and isULA checked only the native IPv6
 ranges. The library already exposed isMapped4() and to4(), but did not apply them inside these checks, so
 a mapped or NAT64 address was never normalized to its embedded IPv4 address before classification. For
 IPv4-mapped addresses the host OS routes to the IPv4 stack, so the misclassification is reachable on any
 dual-stack host. For NAT64, the classification bypass is unconditional but end-to-end reachability
 additionally requires a NAT64/DNS64 gateway in the deployment network.This issue has been fixed in version
 10.2.1. (CVE-2026-54272)

Solution

Update the ip-address library and its related packages to version 10.2.1 or later.
