info ~~critical~~ → info by review dynamic-import defusedxml/common.py:78:5

`__import__` called on a non-literal expression (ast pass, confidence 0.70)
```
    stdlib_name = defused_mod.__origin__
    __import__(stdlib_name, {}, {}, ["*"])
    stdlib_mod = sys.modules[stdlib_name]
    stdlib_names = set(dir(stdlib_mod))
```
likely benign LLM, confidence 0.90 defusedxml's internal helper that dynamically imports the wrapped stdlib XML module by its stored origin name.
Reasoning
The stdlib name comes from `defused_mod.__origin__`, a module attribute set by the package itself, and the code then reads the same module back from sys.modules to collect its names. This is a standard compatibility pattern for wrapping stdlib XML modules, not an attacker-controlled import. The finding is a critical AST dynamic-import hit, but the snippet shows nothing that is hidden, encoded, or fed by external input.
