Summary

Ghost versions from 2.5.0 before 6.64.0 are affected by stored cross-site scripting. Embedding a URL from an attacker-controlled website stores untrusted scripts in post content (CWE-79). A remote attacker can get those scripts to run in the Ghost editor, on the published site and in newsletter emails when a user views the content, possibly compromising a staff user's admin session.

Description from the CNA

Ghost is a Node.js content management system. From 2.1.0 until 6.64.0, embedding a URL from an attacker-controlled website could result in untrusted scripts being stored in post content. These scripts could run in the Ghost editor, on the published site, and in newsletter emails, possibly resulting in compromise of a staff user's admin session. This issue is fixed in version 6.64.0.
