Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the favicon lookup in the OEmbed service, where the metascraper-logo-favicon dependency's default resolver uses reachable-url, which bundles got v11 and bypasses the dnsLookup hook that externalRequest installs to validate resolved IP addresses at connection time. An attacker can exploit this DNS rebinding gap to cause the server to issue requests to internal network resources that would otherwise be blocked by the IP validation logic.
