How to fix?

Upgrade Pillow to version 9.0.0 or higher.


Pillow is a PIL (Python Imaging Library) fork.

Affected versions of this package are vulnerable to Arbitrary Code Execution via PIL.ImageMath.eval which allows evaluation of arbitrary expressions, such as ones that use the Python exec method.
