10. info critical → info by review dynamic-execution setup.py:28:1

    `exec` at module scope (runs on import) on a non-literal expression (ast pass, confidence 0.80)

    version_dict = {}
    exec(d.joinpath("xxhash", "version.py").read_text(), {}, version_dict)
    version = version_dict["VERSION"]

    likely benign LLM, confidence 0.80 setup.py execs the package's own xxhash/version.py to read the VERSION string.

    Reasoning

    The exec reads a version.py file from the package's own directory and pulls out VERSION, which is a common way to get a version string without importing the package during setup. The file path is fixed and local, not attacker-controlled, and nothing in the snippet fetches remote content or hides intent. The module-scope exec is unusual but matches a known legitimate build idiom.

11. info critical → info by review dynamic-import tests/test_interpreters.py:19:19

    `__import__` called on a non-literal expression (ast pass, confidence 0.70)

            try:
                mod = __import__(name)
                if hasattr(mod, 'create'):
                    return mod

    likely benign LLM, confidence 0.85 A test helper calls __import__ on a candidate module name and checks for a 'create' attribute.

    Reasoning

    This is a test helper that dynamically imports a candidate module by name and checks whether it exposes a 'create' attribute, which is how interpreter-backend modules are probed. The name comes from a fixed list of test candidates rather than untrusted input, and the import is not paired with any download or execution chain.
