"This is a Moderate flaw where the `ip-address` JavaScript library incorrectly classifies IPv4-mapped or NAT64 IPv6 addresses. This misclassification can lead to Server-Side Request Forgery (SSRF), allowing an attacker to bypass intended network restrictions and access internal resources. Exploitation is possible on dual-stack hosts for IPv4-mapped addresses, while NAT64 exploitation requires a NAT64/DNS64 gateway.", "threat_severity": "Moderate"}
