A user with permission to edit a page containing a Gallery block can store a caption that executes in the browser of any visitor who opens that image&#39;s lightbox. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 8.5 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N.
