Published:September 15, 2026
Updated:September 22, 2026
Flowise before 3.1.4 fails to enforce workspace-level authorization checks in openai-realtime endpoints, allowing authenticated users to access tools from ChatFlows in other workspaces by supplying an unscoped chatflowid. Attackers can invoke GET and POST requests to retrieve tool definitions and execute tools from victim workspaces, triggering external side effects and accessing sensitive tool outputs.
