Ghost: Cross-Site Scripting in Universal Import
The Universal Import feature in Ghost Admin failed to properly sanitize imported content resulting in XSS in post content.
This vulnerability is present in Ghost from v5.26.0 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.
If your Ghost is a Ghost-CLI install see our documentation on updating it to the latest version here.
If upgrading immediately is not possible, avoid using the Universal Import feature.
