HIGH 7.7REMOTE

CVE-2026-69192 is a high-severity flaw (CVSS 7.7) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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, inet_aton, 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') reports correctForm() of 12.0.0.1 and isPrivate() o
