{"id":"CVE-2026-109352","summary":"LibreNMS before 26.9.0 Stored XSS via wireless sensor description","details":"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.","aliases":["GHSA-ffjc-4fr5-47c6"],"modified":"2026-10-14T02:47:46.341455375Z","published":"2026-10-12T16:05:34.483Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109352.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109352.json"},{"type":"ADVISORY","url":"https://github.com/librenms/librenms/security/advisories/GHSA-ffjc-4fr5-47c6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109352"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/librenms-before-26.9.0-stored-xss-via-wireless-sensor-description"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/librenms/librenms","events":[{"introduced":"0"},{"fixed":"dbe6014c1a0736da12b5f6114d7577c7a9dd136e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"26.9.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["26.8.1","26.8.0","26.7.0","26.6.0","26.5.1","26.5.0","26.4.1","26.4.0","26.3.1","26.3.0","26.2.0","26.1.0","25.12.0","25.11.0","25.10.0","25.9.0","25.8.0","25.7.0","25.6.0","25.5.0","25.4.0","25.3.0","25.2.0","25.1.0","24.12.0","24.11.0","24.10.1","24.10.0","24.9.1","24.9.0","24.8.0","24.7.0","24.6.0","24.5.0","24.4.1","24.4.0","24.3.0","24.2.0","24.1.0","23.11.0","23.10.0","23.9.1","23.9.0","23.8.2","23.8.1","23.8.0","23.7.0","23.6.0","23.5.0","23.4.1","23.4.0","23.2.0","23.1.0","22.12.0","22.11.0","22.10.0","22.9.0","22.8.0","22.7.0","22.6.0","22.5.0","22.4.0","22.3.0","22.2.1","22.2.0","22.1.0","21.12.1","21.12.0","21.11.0","21.10.0","21.9.0","21.8.0","21.7.0","21.6.0","21.5.1","21.5.0","21.4.0","21.3.0","21.2.0","21.1.0","1.70.1","1.70.0","1.69","1.68","1.67","1.66","1.65","1.64.1","1.64","1.63","1.62","1.61","1.60","1.59","1.58.1","1.58","1.57","1.56","1.55","1.54","1.53.1","1.53","1.52","1.51","1.50","1.49","1.48.1","1.48","1.47","1.46","1.45","1.44","1.43","1.42.01","1.42","1.41","1.40","1.39","1.38","1.37","1.36","1.35","1.33","1.32","1.31.03","1.31.02","1.31.01","1.28","1.27","1.26","1.25","1.21","201609","1.20","20160828","1.19","201608","201607","201606","201605","201604","201603","201602","201601","201512","201511","201510","201509","201508","201507","201505","201506","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109352.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]}
