AI-Generated

Ghost, a Node.js content management system, is vulnerable to a flaw that allows staff users, including Contributors, to store non-image files as bookmark icons or thumbnails. This could lead to the hosting of arbitrary HTML on the site's domain, potentially compromising the admin sessions of other staff users. Organizations using Ghost versions 5.94.0 to 6.64.0 should prioritize upgrading to version 6.64.0 to mitigate this high-severity risk.

Original NVD Description

Ghost is a Node.js content management system. From 5.94.0 until 6.64.0, when creating a bookmark card, Ghost could store non-image files fetched from an external website as bookmark icons or thumbnails. This allowed any staff user, including Contributors, to host arbitrary HTML on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.64.0.
