CVE-2026-61643 FastGPT: workflow runtime can execute another user's private HTTP toolset

FastGPT is a knowledge-based AI application platform. From 4.14.17 until 4.15.0-beta5, an authenticated FastGPT user can save a workflow node that points to another user's private HTTP toolset by using a crafted saved tool id such as http-/. The normal toolset routes deny access, but the workflow...
