CVE-2026-34162

CRITICAL

FastGPT: Unauthenticated SSRF via httpTools Endpoint Leads to Internal API Key Theft

Title source: cna
STIX 2.1

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.
