Vulnerability Title
FastGPT: SSRF Vulnerability in Laf Workflow Node via Missing Internal Address Validation
Source: NVD (National Vulnerability Database)
Vulnerability Description
FastGPT is an AI Agent building platform. Prior to version 4.14.17, an unauthenticated Server-Side Request Forgery (SSRF) vulnerability allows attackers (or authenticated users with App editing privileges) to send arbitrary HTTP requests to internal/private network addresses. The fetchData function in the lafModule workflow node uses axios to fetch user-controlled URLs without validating them against the application's internal network blocklist guard (isInternalAddress), bypassing SSRF protections. This issue has been patched in version 4.14.17.
