NVD Description
Note: Versions mentioned in the description apply only to the upstream ghost package and not the ghost package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
Ghost is a Node.js content management system. From version 6.34.0 until 6.67.0, embed cards in the Ghost editor could bypass protections against stored cross-site scripting. Any staff user, including Contributors, could store scripts in post content that ran when another staff user opened the post in the editor, potentially compromising that user’s admin session. Self-hosted sites should leave the new security.embedPreviewUrl configuration option at its default value. This issue is fixed in version 6.67.0.
