Snipe-IT before 8.7.0 contains a server-side request forgery vulnerability in the webhook testing feature that allows super-admin users to probe internal network addresses, including loopback and RFC1918 ranges. Attackers can point webhooks at internal hosts and ports, then compare 4xx versus 5xx responses from Test Webhooks to map open ports and active hosts.
