A cross-site scripting (XSS) vulnerability exists in TryGhost Ghost when creating bookmark cards. Non-image files fetched from external websites could be stored as bookmark icons or thumbnails, allowing any staff user, including Contributors, to host arbitrary HTML on the site's domain. This may lead to compromise of other staff users' admin sessions. The vulnerability affects Ghost versions from 5.94.0 up to but not including 6.64.0. Version 6.64.0 contains a fix for this issue.
