| Title | vanna-ai vanna 2.0.2 Missing Authentication on All API Endpoints |
|---|
| Description | Vanna <= 2.0.2 does not implement any authentication mechanism at the HTTP layer for its API endpoints. The /api/vanna/v2/chat_poll, /api/vanna/v2/chat_sse, and /api/vanna/v2/chat_websocket endpoints accept requests from any client without requiring an Authorization header, API key, session token, or any other form of authentication. When configured with a real LLM and database, this allows unauthenticated attackers to execute arbitrary natural language queries against the connected database. |
