The server uses parameterized queries (`aiosqlite`) to prevent SQL injection. Sensitive credentials are read from environment variables, avoiding hardcoding. Pydantic models are used for input validation, mitigating common injection risks. The Feishu event webhook has basic token validation, and explicitly notes that encryption is not implemented, meaning it won't attempt to process encrypted payloads without the `ENCRYPT_KEY` being set, which is a safe default. File system operations are primarily on internally managed paths (`entries/`). External API calls are handled by `httpx`, a standard and secure library. No obvious `eval` or `exec` vulnerabilities in user-controlled paths were found. The primary risk would stem from misconfiguration of Feishu API permissions or the webhook exposing itself publicly without robust access controls.
