mcp-raganything

The server has several potential security concerns: - **Arbitrary File Uploads:** The `/api/v1/file/index` endpoint allows users to upload arbitrary files to a temporary directory (`/tmp/output`). While basic path traversal for the file path is mitigated, there is no explicit content validation or type checking. Maliciously crafted documents (e.g., PDFs, DOCX) could exploit vulnerabilities in the underlying `Docling` or `raganything` parsing libraries, potentially leading to denial-of-service, resource exhaustion, or remote code execution. - **Permissive CORS:** The `ALLOWED_ORIGINS` defaults to `"*"`, which is overly permissive for a production environment and could expose the API to unintended cross-origin requests. - **Untrusted LightRAG API URL:** The application fetches and merges the LightRAG server's OpenAPI specification from `LIGHTRAG_API_URL` during startup. If this URL is controlled by an attacker, it could be used to inject malicious content into the API documentation, cause denial-of-service during startup (if the URL points to a slow/malicious server), or potentially leak information. - **Proxying Authorization Headers:** The application forwards `Authorization` and `api_key_header_value` headers to the LightRAG server. While intended functionality, this means the security of the overall system is dependent on the trustworthiness and security of the configured LightRAG server.
