Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the is_global_address function. An attacker can access internal network resources or sensitive endpoints by supplying specially crafted IPv6 addresses that are interpreted as globally routable, allowing bypass of network access controls. This is only exploitable if the host network supports 6to4 routing, has a NAT64 gateway, or resolves IPv6 transition forms to internal IPv4 endpoints.
