公告说明

Impact

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.

Vulnerable versions

This vulnerability is present in Ghost from v0.10.0 up to v6.54.0.

Patches

v6.54.1 contains a fix for this issue.

How to update

For self-hosters using Docker, find Docker's official Ghost image here. Updating a Docker-based Ghost instance is documented here.

If your Ghost is a Ghost-CLI install see our documentation on updating it to the latest version here.
