hello3dmcp-frontend

The frontend itself does not contain obvious critical vulnerabilities like `eval` or direct unsanitized HTML injection. It uses WebSockets to communicate with an external MCP server, handling incoming commands as JSON. The primary security considerations are: 1. **Trust in MCP Server**: The frontend relies entirely on the MCP server (`hello3dmcp-server`) for valid and non-malicious commands. If the server is compromised or provides malformed commands, it could lead to unexpected client-side behavior or crashes, though likely not remote code execution on the client. 2. **`sessionId` Management**: The `sessionId` is extracted from URL parameters and used for WebSocket registration. The security of session management is critical and primarily handled by the MCP server. If session IDs are easily predictable or guessable, it could lead to unauthorized control. 3. **`VITE_WS_URL` Configuration**: In production, the WebSocket URL is configured via `VITE_WS_URL`. If this environment variable is misconfigured to point to a malicious WebSocket server, the client could be compromised by malicious commands. 4. **Input Validation**: While basic type checks are present for some parameters (e.g., `parseInt` for color hex), robust validation of all incoming command parameters against expected ranges or formats is not explicitly detailed, which could lead to runtime errors if the MCP server sends invalid data.
