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.\n\n\nThe fix changes:\n\n\ntitleEl.innerHTML = arg.event.title\n\n\nto:\n\n\ntitleEl.textContent = arg.event.title || ''\n\nand similarly stops using innerHTML for the static download icon.\n\nVersion impacted =\u003e3.3.0",
