CVE-2020-15271
Users that use lookatme to render untrusted markdown may have malicious shell commands automatically run on their system.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In lookatme (python/pypi package) versions prior to 2.3.0, the package 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. This is fixed in version 2.3.0. As a workaround, 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.
