CVE-2026-63730Public exploitNetwork attack vector

Authenticated SSRF via incomplete hostname blacklist

Published Jul 20, 2026 · Updated Jul 20, 2026

Server-side request forgery in HyperDX before 2.31.0 allows remote authenticated users to reach internal services via webhook tests. The POST /webhooks/test path passes caller-supplied generic and IncidentIO URLs to fetch after validateWebhookUrl blocks only configured database hostnames, not private, loopback, link-local, or IPv6 literals. Any team member can use the server's network position to enumerate internal services or request cloud instance metadata.
