Concrete CMS before 9.5.3 rendered Express entry labels as raw HTML when displaying associated entries, resulting in stored cross-site scripting. An unauthenticated attacker could submit a payload through a public Express Form; it then executed in an administrator’s dashboard session when the associated entry was viewed, or in the browser of any visitor to a page using an Express Entry List block with association columns, allowing actions to be performed with that user’s privileges.\u00a0The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.3 with vector CVSS:4.0\/AV:N\/AC:L\/AT:P\/PR:N\/UI:P\/VC:L\/VI:L\/VA:N\/SC:N\/SI:N\/SA:N.
