CVE-2026-84189

CVE-2026-84189 · LibreNMS before 26.7.0 Stored XSS via Oxidized API

This page contains facts from public vulnerability sources. Check the original advisory before updating.

LibreNMS through 26.4.0 renders JSON fields (name, ip, model, author, commit message) returned by the admin-configurable Oxidized integration URL (oxidized.url) into the device showconfig page without applying htmlspecialchars(). An administrator who points the Oxidized URL at an attacker-controlled server (SSRF) can cause it to return malicious JSON, resulting in stored/persistent cross-site scripting affecting all users who view any device's showconfig tab. Fixed in 26.7.0.
