    "summary": "Flowise has Authorization Bypass via Spoofed x-request-from Header\nFlowise trusts any HTTP client that sets the header `x-request-from: internal`, allowing an authenticated tenant session to bypass all `/api/v1/**` authorization checks. With only a browser cookie, a low-privilege tenant can invoke internal administration endpoints (API key management, credential stores, custom function execution, etc.), effectively escalating privileges.",
