Ghost from 5.94.0 before 6.64.0 contains a stored cross-site scripting vulnerability that allows staff users, including Contributors, to host arbitrary HTML by abusing bookmark card image fetching. Attackers can create bookmark cards that store non-image files from external websites as icons or thumbnails to compromise other staff users' admin sessions.
