UBUNTU-CVE-2026-69192

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.3.1, Address4 accepts an octet written with a leading zero and decodes it as decimal, while the WHATWG URL host parser, inetaton, and getaddrinfo all decode a leading zero as octal. The library...

GHSA-MWP4-54F8-5FHR ip-address: Address4 decodes leading-zero octets as decimal while resolvers decode them as octal, allowing SSRF and trust-boundary bypass

Summary Address4 accepts an octet written with a leading zero and decodes it as decimal, while the WHATWG URL host parser, inetaton, and getaddrinfo all decode a leading zero as octal. The library and the network stack therefore disagree about which host a string names. new Address4'012.0.0.1'...

CVE-2026-69192

IP-address Address4 in JavaScript is vulnerable prior to 10.3.1 because a leading-zero octet is decoded as decimal, while the host resolver stack decodes as octal. This mismatch causes misclassification of hosts for trust-boundary decisions (e.g., SSRF filtering) since isPrivate(), isLoopback(), ...
