CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:NLibreNMS is a network monitoring system. In versions up to and including 26.4.0, the Proxmox application view is vulnerable to reflected cross-site scripting through the user-supplied instance and vmid GET parameters, which are reflected into the page title without adequate encoding.

This issue is fixed in version 26.5.0.
Multiple vulnerabilities have been discovered in LibreNMS, allowing attackers to execute arbitrary code remotely, perform server-side request forgery (SSRF), and inject code remotely via XSS. These vulnerabilities affect…
