LibreNMS before 26.9.0 contains a stored cross-site scripting vulnerability in includes/html/pages/device/wireless.inc.php, which echoes wireless sensor sensor_descr values, populated from SNMP DisplayString fields during discovery, into HTML without escaping. Attackers controlling a monitored device's SNMP agent can set values such as AI-AP-MIB::aiSSID to malicious JavaScript that executes when authenticated users view the device's Wireless tab, enabling session hijacking.
