Concrete CMS before 9.5.3 did not validate an anti-CSRF token in the Calendar event duplicate dialog controller (concrete\/controllers\/dialog\/event\/duplicate.php) submit() action, which duplicated a calendar event after checking only canAccess() and the per-resource canAddCalendarEvent() permission, so a crafted cross-site request could cause an authenticated user with add-event permission to create duplicate CalendarEvents and CalendarEventVersions records under their own authority.\u00a0The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.3 with vector CVSS:4.0\/AV:N\/AC:L\/AT:N\/PR:N\/UI:P\/VC:N\/VI:L\/VA:N\/SC:N\/SI:N\/SA:N.\u00a0Thanks Winston Crooker\u00a0for reporting.<\/p>\n","protected":false},"excerpt":{"rendered":"
