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 0.85 A dynamic __import__ of the stdlib module whose name is stored in the defused module's __origin__ attribute, used to mirror its names.
Reasoning
The __import__ target comes from defused_mod.__origin__, which is the stdlib module name that defusedxml wraps. The code imports that stdlib module and copies its public names into the defused module, a common compatibility shim. The dynamic import is driven by the package's own module metadata, not by external or attacker-controlled input, and nothing in the snippet decodes, downloads, or executes a payload. The critical severity comes from the generic dynamic-import signal, not from anything suspicious in this code.
