CVE-2025-65013: LibreNMS vulnerable to Reflected Cross-Site Scripting (XSS) in endpoint `/maps/nodeimage` parameter `Image Name`

CVE-2025-65013 · Severity: medium · CVSS 6.2 · Published 2025-11-18

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring tool. Prior to version 25.11.0, a reflected cross-site scripting (XSS) vulnerability was identified in the LibreNMS application at the /maps/nodeimage endpoint. The Image Name parameter is reflected in the HTTP response without proper output encoding or sanitization, allowing an attacker to craft a URL that, when visited by a victim, causes arbitrary JavaScript execution in the victim’s browser. This issue has been patched in version 25.11.0.

Technologies: Librenms, librenms/librenms (Packagist). Vendors: Librenms, Packagist.
