## Overview

Budibase through 3.41.0 contains a server-side request forgery vulnerability in AI table generation because the uploadUrl function in packages/server/src/utilities/fileUtils.ts uses raw node-fetch instead of fetchWithBlacklist. Authenticated builder users can send a prompt to POST /api/ai/tables that places an internal URL in an attachment column, causing the server to fetch it and return a presigned object-storage URL containing the response, such as cloud metadata credentials.
