ip-address: isInSubnet() and isHostInSubnet() compare addresses of different families as if they shared an address space, allowing an allowlist check to admit an address outside its range

Summary isInSubnet and isHostInSubnet accept an address of either family and compare masked binary strings without checking that both operands are the same family. Address4 pads to 32 bits and Address6 to 128, so whenever the leading bits agree the strings are equal: new...

Allocation of Resources Without Limits or Throttling

Overview 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 Allocation of Resources Without Limits or Throttling via the Address6.isValid method and the Address4 constructor when parsing an oversized input...

DEBIAN-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...
