A Server-Side Request Forgery (SSRF) vulnerability exists in Hugo versions 0.162.0 through 0.163.0, where the 'security.http.urls' policy designed to deny requests to loopback, internal, and cloud-metadata IPv4 literals could be bypassed as the policy only matched dotted-decimal notation, allowing alternate IPv4 encodings (integer, hex, octal) to pass, enabling build-time server-side requests to internal services and cloud-metadata endpoints when untrusted or data-derived URLs are passed to 'resources.GetRemote'.
