CVE-2023-36088Public exploitNetwork attack vector

Internal service discovery via unchecked connection targets

Published Sep 1, 2023 · Updated Jul 9, 2026

Server-side request forgery in NebulaGraph Studio 3.7.0 allows remote attackers to discover internal services through the login interface. The unauthenticated /api-nebula/db/connect endpoint accepts attacker-controlled address and port values, attempts the connection, and returns distinguishable responses and status codes. No account or user interaction is required; the exposed service becomes a proxy for enumerating reachable intranet hosts and open ports, with no demonstrated data retrieval beyond connection-status information.
