Name of the Vulnerable Software and Affected Versions Ghost versions 5.94.0 through 6.63.0

Description A stored cross-site scripting issue exists that allows staff users, such as Contributors, to host arbitrary HTML. This is achieved by abusing the bookmark card image fetching mechanism, where attackers can create bookmark cards that store non-image files from external websites as icons or thumbnails to compromise the admin sessions of other staff users.

Recommendations Update Ghost to version 6.64.0 or later.
