An issue exists in the Server-Side Request Forgery (SSRF) protection within the `AddressPredicate.java` file. While the system blocks the RFC 6052 64:ff9b::/96 NAT64 prefix, it fails to block the RFC 8215 64:ff9b:1::/48 local-use prefix. On dual-stack servers utilizing RFC 8215 NAT64, an unauthenticated user capable of executing Lua code can utilize the `http.request` or `http.websocket` functions with an address under 64:ff9b:1::/48 to access loopback, RFC 1918, cloud metadata, or internal API endpoints. This occurs because the `PrivatePattern.matches()` function does not correctly classify the mapped IPv6 address as private.
