CVE-2026-61646
FastGPT is a knowledge-based AI application platform.
Overview
CVE-2026-61646 is a known-severity vulnerability. It was published on July 15, 2026.
Technical 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.
