No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

HyperDX before 2.31.0 contains a server-side request forgery vulnerability that allows authenticated team members to direct the server to make requests to arbitrary internal network destinations by supplying a caller-controlled URL to the webhook test endpoint. Attackers can bypass the insufficient hostname blacklist validation in the webhook handler to enumerate internal services, interact with internal containers, or access cloud instance metadata services including provider metadata endpoints.
