## Description

The WPGraphQL plugin for WordPress is vulnerable to Server-Side Request Forgery via the media item creation mutation's remote file URL in all versions up to, and including, 2.24.1 due to an incomplete safe-URL check. A failed AAAA (IPv6) DNS lookup was treated as a host with no IPv6 addresses, and the NAT64 local-use prefix (64:ff9b::/32 outside the well-known /96 prefix) was not blocked. This makes it possible for authenticated attackers with Author-level access and above, who can upload media, to make web requests to internal addresses and possibly query or modify internal services, under conditions such as a failing IPv6 resolver or a network using a local NAT64 translator.
