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/fileloader.py files may be manually deleted. Additionally, it is always recommended to be aware of what is being rendered with lookatme.
