Description (CNA)
pfSense Plus before 26.07 and pfSense CE through 2.8.1 contain a stored cross-site scripting vulnerability in the Traffic Graphs top-talkers feature, where PTR records returned by reverse DNS lookups are incorporated without sanitization into AJAX responses and rendered as HTML through a DOM sink in the administrator interface. An attacker who controls a PTR record and generates sufficient traffic to appear as a top talker can execute arbitrary JavaScript in an administrator's browser, gaining access to the authenticated session context and same-origin access to the firewall management interface, enabling account creation and arbitrary OS command execution.
