ip-address: ip-address: Inconsistent IP address parsing leads to Server-Side Request Forgery (SSRF) and trust-boundary bypass

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...

ip-address: ip-address: Server-Side Request Forgery via IPv4-mapped/NAT64 IPv6 address misclassification

A flaw was found in the ip-address library. This library, used for parsing and manipulating IPv4 and IPv6 addresses in JavaScript, is vulnerable to Server-Side Request Forgery SSRF due to incorrect classification of IPv4-mapped/NAT64 IPv6 addresses. An attacker could exploit this misclassificatio...
