Upgrade ghost to version 6.51.0 or higher.
Overview
ghost is a publishing platform
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via image dimension refetching, where Ghost re-fetches missing image dimensions by issuing an outbound HTTP request to the URL stored on an image card without restricting that URL to trusted image hosts. An authenticated staff user who can create or edit posts can point an image card at an arbitrary host, causing the Ghost server to issue HTTP requests on their behalf. This includes internal network endpoints and cloud instance metadata services that are not reachable from the public internet.
