CVE-2026-69198

A flaw was found in ip-address, a JavaScript library for parsing and manipulating IP addresses. By appending a Classless Inter-Domain Routing CIDR suffix to an IP address, an attacker can bypass the library's special-use classification methods. This misclassification can lead applications, such a...

CVE-2026-69198

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.1.1 until 10.2.2, every special-use classification method is built on isInSubnet, which short-circuits to false whenever the address's own subnet mask is shorter than the reference range's mask. Th...

Server-side Request Forgery (SSRF)

Overview org.webjars.npm:ip-address is an A library for parsing IPv4 and IPv6 IP addresses in node and the browser. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the isInSubnet function. An attacker can bypass network trust-boundary checks by appending a...

ip-address: a CIDR suffix on the parsed address suppresses special-use classification and can bypass SSRF and trust-boundary checks

Summary Every special-use classification method is built on isInSubnet, which short-circuits to false whenever the address's own subnet mask is shorter than the reference range's mask. That mask comes verbatim from the CIDR suffix on the parsed input, so appending a suffix such as /0 suppresses...

CVE-2026-69198

The CVE affects the ip-address JavaScript library (versions 10.1.1–10.2.2). A defect in the containment guard in classification (built on isInSubnet) makes special-use checks (isLoopback, isPrivate, isLinkLocal, isCGNAT, isMulticast, isUnspecified, isBroadcast, isULA, getType) return an internal ...
