CVE-2026-69192· NVD / CVE Program· CNA GitHub_M

ip-address: Address4 decodes leading-zero octets as decimal while resolvers decode them as octal, allowing SSRF and trust-boundary bypass

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.62% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: beaugunderson ip-address 10.3.1.

Low priority for now. Upgrade to beaugunderson ip-address 10.3.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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() of false, but fetch('http://012.0.0.1/') connects to 10.0.0.1. An application that builds a network trust-boundary decision on these checks, for example a filter intended to block Server-Side Request Forgery, or SSRF, will classify an internal target as external and allow the request. The defect is in the parse gate rather than in any one classifier, so every consumer of Address4 inherits it: isPrivate(), isLoopback(), isLinkLocal(), isCGNAT(), isInSubnet(), isHostInSubnet(), and correctForm() are all computed from the mis-decoded octets. This issue is fixed in version 10.3.1.
