A Server-Side Request Forgery (SSRF) in Ghost Admin allowed any staff-level user to perform a blind HTTP GET request against internal hosts. No output was returned, but this could have been used to probe open ports on internal hosts.
This vulnerability is present in Ghost from v0.10.0 up to v6.54.0.
v6.54.1 contains a fix for this issue.
For self-hosters using Docker, find Docker's official Ghost image here. Updating a Docker-based Ghost instance is documented here.
