CVE-2025-65013: Librenms

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
