Overview
Affected versions of this package are vulnerable to Remote Code Execution (RCE). The package allows access to Python's string module, which then allows access to the Formatter class that can be overridden in a way that allows access to further unsafe Python libraries.
NOTE: This only applies to Python 3. Furthermore, only websites that allow untrusted users to edit Script (Python) are vulnerable.
