Summary
Markdown-supplied Shell Command Execution
Details

Impact

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.

Patches

Users should upgrade to lookatme versions 2.3.0 or above.

Workarounds

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.
