In Concrete CMS below version 9.5.3, the Address attribute’s country-less text formatter skipped HTML-escaping, enabling stored XSS in Express association views. A user able to submit an Address attribute could execute script in the session of any dashboard user who opened the affected entry. The unescaped branch was reachable because a non-required Address attribute accepted a blank country, and because several Express association templates (for example concrete\/elements\/express\/form\/view\/dashboard\/association.php) echoed the association label mask without applying h().\u00a0The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 7.5 with vector CVSS:4.0\/AV:N\/AC:L\/AT:P\/PR:L\/UI:P\/VC:H\/VI:H\/VA:H\/SC:N\/SI:N\/SA:N.
