LibreNMS through 26.9.1.1 contains an authorization bypass vulnerability in includes/html/graphs/smokeping/auth.inc.php that checks the src probe device instead of the rendered target device. Restricted users permitted on a probe device can request smokeping_in or smokeping_out graphs with arbitrary device ids to view latency data and enumerate device names.
