The `src/golf/examples/basic/tools/calculator.py` tool uses `eval()` to evaluate mathematical expressions. While it attempts to sanitize input with a character whitelist, `eval()` is inherently dangerous when processing untrusted input as it can lead to arbitrary code execution if not handled with extreme care and robust sanitization. The framework dynamically loads and executes user-provided `startup.py`, `middleware.py`, `health.py`, and `readiness.py` files, which means the overall security of a deployed server heavily depends on the security practices within the user's own project code. A default PostHog API key for anonymous telemetry is hardcoded in `src/golf/core/telemetry.py`, though it's a public client-side key and can be overridden by an environment variable. OAuth configurations include robust URL validation to mitigate SSRF and enforce HTTPS in production, which is a good security practice.
