CVE-2026-84189 (opens in a new tab)How to fix?
Upgrade librenms/librenms to version 26.7.0 or higher.
Overview
librenms/librenms is a fully featured network monitoring system that provides a wealth of features and device support.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the processing of JSON fields from an external API response in the device showconfig page. An attacker can execute arbitrary JavaScript in the context of users' browsers by supplying crafted data in the name, ip, model, author, or commit message fields, which are rendered without proper escaping. This is only exploitable if an administrator configures the integration URL to point to an attacker-controlled server and the Oxidized integration is enabled.
