An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the pymatgen PyPI package, when an attacker is able to supply arbitrary input to the GaussianInput.from_string method
Weakness
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
