What it is

LibreNMS before 26.9.0 contains a missing authorization vulnerability in PortsController::purge that allows global-read users to physically delete ports without delete privileges. Attackers with read-only accounts can send DELETE requests to /ports/purge, using purge=all to irreversibly erase every deleted port on all visible devices.
