Description

Affected versions of Flowintel render calendar event titles using innerHTML. Because those titles are derived from case titles, a user able to create or modify a case title could store HTML or script-capable content that is later interpreted by the browser when another user views the calendar. The fix changes: titleEl.innerHTML = arg.event.title to: titleEl.textContent = arg.event.title || '' and similarly stops using innerHTML for the static download icon. Version impacted =>3.3.0
