## Overview

Budibase is an open-source low-code platform. Prior to 3.39.32, GET /api/global/users/tenant/:id was listed in PUBLIC_ENDPOINTS in packages/worker/src/api/index.ts, and tenantUserLookup returned a full PlatformUser document. An unauthenticated caller could query an email or user identifier, distinguish existing users from missing users, and obtain tenant identifiers, user identifiers, email addresses, SSO identifiers, and document revision metadata. This issue is fixed in version 3.39.32.
