Summary
Ghost: Session Fixation in Ghost Admin
Details

Impact

Ghost Admin did not invalidate existing sessions on login which could have allowed for session fixation attacks. Successful exploitation would have required another vulnerability on the same domain where Ghost Admin was hosted.

Vulnerable versions

This vulnerability is present in Ghost from v2.2.0 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.
