CVE-2026-109352

5.3 medium SSVC exploitation: poc Awaiting Analysis
NVD · CVE.org

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.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
