Summary
LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system.

This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions. This vulnerability is fixed in 24.9.0.
