## Overview

Budibase before 3.45.0 fails to properly scope the GET /api/chat-links endpoint by workspace, allowing builders to enumerate chat identity link records across all workspaces in a tenant. Attackers with builder access to a single workspace can retrieve sensitive chat identity linking data including user IDs and external chat service identifiers from other workspaces they have no permission to access.
