GHSA-c2c9-mfw7-p8hw: Flowise: Cross-Workspace Chatflow Disclosure via chatflows/apikey Endpoint Returns All Unprotected Chatflows

The /api/v1/chatflows/apikey/:apikey endpoint (whitelisted, accessible with API key auth only) returns all chatflows bound to the provided API key AND all chatflows across the entire system that have no API key assigned. This crosses workspace boundaries, allowing a user in Workspace A who has a valid API key to read the full configuration (including flowData, chatbotConfig, system prompts, and node configurations) of chatflows from Workspace B, Workspace C, and all other workspaces, as long as those chatflows have no API key assigned.
