LibreNMS before 26.7.0 Stored XSS via Oxidized API
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.

librenms before 26.7.0 Stored XSS via graph_descr settings
LibreNMS versions <= 26.4.0 contain a stored cross-site scripting vulnerability in the graph_descr.<graphtype> configuration settings, which are echoed verbatim without HTML escaping in includes/html/pages/graphs.inc.php. An administrator can store a malicious HTML payload that executes in the browser of any authenticated user who views the affected graph type. The issue is fixed in version 26.7.0.
