CVE-2026-61646

FastGPT: Shared axios SSRF guard validates only the initial URL before following redirects

Published Jul 15, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
FastGPT is a knowledge-based AI application platform. Prior to 4.15.0-beta5, FastGPT's shared SSRF guard validates only the initial request URL before handing the request to axios, and axios follows redirects by default. An authenticated workflow user can configure an HTTP request node to call an attacker-controlled public URL that redirects to cloud metadata, loopback, or internal services that the guard would block on direct request, and the HTTP node returns the response body to the workflow caller. This issue is fixed in version 4.15.0-beta5.
