Pymatgen (Python Materials Genomics) is an open-source Python library for materials analysis. A critical security vulnerability exists in the JonesFaithfulTransformation.from_transformation_str() method within the pymatgen library prior to version 2024.2.20. This method insecurely utilizes eval() for processing input, enabling execution of arbitrary code when parsing untrusted input. Version 2024.2.20 fixes this issue.
