ecosystem impact- 6 npm packages depend on ip-address (5 direct, 1 indirect)
Ecosystem-wide dependent count for version 10.2.0.
DescriptionCVE.org
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.
AnalysisAI
The JavaScript library ip-address (npm) fails to treat the NAT64 local-use prefix 64:ff9b:1::/48 as private, so applications that lean on Address6.isPrivate - typically together with isLoopback and isLinkLocal - to enforce an SSRF or trust-boundary policy can be tricked into reading an internal IPv4 destination as external. Unauthenticated network attackers can exploit this (CVSS v4.0 6.9; independent assessment CVSS v3.1 AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N) only when the target server's network actually uses an operator-chosen NAT64 prefix carved from the RFC 8215 local-use range, and only when the consuming application composes these classifiers as a security control; information disclosure is the realistic outcome, with no impact on integrity or availability. …

Vulnerability AssessmentAI
| Exploitation | Requires all of: (1) the consuming application calls Address6.isPrivate (typically alongside isLoopback/isLinkLocal) to make a trust-boundary/SSRF decision, and (2) the server's network uses an operator-selected NAT64 prefix that falls within the RFC 8215 local-use range 64:ff9b:1::/48. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but narrowly-scoped SSRF-adjacent trust-boundary bypass, not a high-CVSS/low-real-risk phantom. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: 10.5.1 - upgrade ip-address to 10.5.1 or later, which makes Address6.isPrivate return true for the whole RFC 8215 local-use range 64:ff9b:1::/48 (see GHSA-2vr4-cq9g-pvrc, commit ab3dc88bcf5374344168a2ba075ca7ac4ff257f8, and the v10.5.1 release notes). … Detailed patch versions, workarounds, and compensating controls in full report. |
