CVE-2025-65013Public exploitNetwork attack vector

JavaScript execution via unencoded Image Name reflection

Published Nov 18, 2025 · Updated Nov 19, 2025

Reflected XSS in LibreNMS before 25.11.0 allows remote authenticated users to execute JavaScript via the Image Name parameter. The /maps/nodeimage handler inserts the request value into its generated response without contextual output encoding, so the browser parses attacker-controlled markup. Exploitation requires node-image management access and a victim to visit the crafted URL, exposing data and actions available in that victim's session.
