🎯 What:

Fixed a security vulnerability where the Crawlith UI dashboard was binding to 0.0.0.0 by default, making it accessible to anyone on the same network.

⚠️ Risk:

Leaving the dashboard exposed on all interfaces could allow unauthorized users on the network to access internal crawl data and site analysis results.

πŸ›‘οΈ Solution:

  • Default the server binding to 127.0.0.1.
  • Added a --host CLI option to allow users to override this behavior when remote access is explicitly required (e.g., in containerized environments).
  • Added unit tests to ensure the host binding logic works as expected.

This commit addresses a security vulnerability where the unauthenticated
dashboard was exposed on all network interfaces by default.

Changes:
- Modified @crawlith/server to default to binding to '127.0.0.1' instead of all interfaces (0.0.0.0).
- Updated @crawlith/cli to include a `--host` option for the `ui` command, allowing users to explicitly request binding to a different interface if needed.
- Added unit tests to verify the default and configurable host binding.
- Updated the server's console logs to accurately reflect the host it is binding to.
