Vulnerability Title
FastGPT: Unauthenticated SSRF via httpTools Endpoint Leads to Internal API Key Theft
Source: NVD (National Vulnerability Database)
Vulnerability Description
FastGPT is an AI Agent building platform. Prior to version 4.14.9.5, the FastGPT HTTP tools testing endpoint (/api/core/app/httpTools/runTool) is exposed without any authentication. This endpoint acts as a full HTTP proxy — it accepts a user-supplied baseUrl, toolPath, HTTP method, custom headers, and body, then makes a server-side HTTP request and returns the complete response to the caller. This issue has been patched in version 4.14.9.5.
