Fastgpt · Fastgpt · CVE-2026-34162
Name of the Vulnerable Software and Affected Versions
FastGPT versions prior to 4.14.9.5
Description
FastGPT is an AI Agent building platform. The HTTP tools testing endpoint ('/api/core/app/httpTools/runTool') was exposed without authentication in versions prior to 4.14.9.5. This endpoint functions as a full HTTP proxy, accepting a user-supplied `baseUrl`, `toolPath`, HTTP method, custom headers, and body, then making a server-side HTTP request and returning the complete response. This allows an unauthenticated attacker to potentially exfiltrate API tokens, access internal services, and send arbitrary HTTP requests. This issue enables a Server-Side Request Forgery (SSRF) condition, potentially leading to Remote Code Execution (RCE).
Recommendations
Update FastGPT to version 4.14.9.5 or later.
