lookatme versions prior to 2.3.0 automatically loaded the built-in "terminal" and "file_loader" extensions. Users that use lookatme to render untrusted markdown may have malicious shell commands automatically run on their system.
Users should upgrade to lookatme versions 2.3.0 or above.
The lookatme/contrib/terminal.py and lookatme/contrib/file_loader.py files may be manually deleted. Additionally, it is always recommended to be aware of what is being rendered with lookatme.
