How to fix?

Upgrade static-eval to version 2.0.0 or higher.


static-eval is a module to evaluate statically-analyzable expressions.

Affected versions of the package are vulnerable to Arbitrary Code Execution. If un-sanitized user input is passed to static-eval, it is possible to break out of the sandboxed instance, and execute arbitrary code from the standard library.
