Description

A flaw was found in the ip-address library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass security measures like Server-Side Request Forgery (SSRF) filters and potentially gain unauthorized access to internal systems.

Statement

This Important flaw in the ip-address JavaScript library can lead to Server-Side Request Forgery (SSRF) and trust-boundary bypass. The library's inconsistent parsing of IP address octets with leading zeros, which it interprets as decimal while the network stack interprets them as octal, can cause applications to misclassify internal IP addresses as external. This discrepancy can bypass security filters designed to prevent access to internal resources.
