CVE-2026-44286Public exploitNetwork attack vector

Internal service requests via unvalidated Laf URL

Published May 8, 2026 · Updated May 8, 2026

SSRF in the Laf workflow node in FastGPT before 4.14.17 allows remote attackers to send HTTP requests to private network addresses. The fetchData function passes a user-controlled absolute system_httpReqUrl to axios without applying the isInternalAddress guard, so axios ignores the intended local base URL. A crafted workflow graph or node-injection request reaches the sink and returns internal service responses; state changes require permissive internal endpoints.
