CVE-2026-33693: Rust Ipv4 Missing Unspecified Check
IPv4 validation missing `is_unspecified()` check. When checking whether an IP address is private or loopback to prevent Server-Side Request Forgery (SSRF), failing to block the unspecified address (`0.0.0.0` or `Ipv4Addr::UNSPECIFIED`) can allow attackers to bypass protections. On some operating systems (like Linux), traffic destined to `0.0.0.0` is routed t
