My patch for issue #11133 introduced a regression: it is no longer possible to get attributes of modules. That is because modules use "tp_dictoffset" (at C level). The instance __dict__ is exposed to Python code using a types.MemberDescriptorType. My patch for issue #11133 currently assumes that accessing the instance __dict__ can trigger code execution, but that is impossible: The access itself can't trigger code execution (it just returns a PyObject in the C struct). Theoretically, it could return any Python object, but that doesn't matter, as the code that uses the object only calls dict methods directly, hence a TypeError is the worst thing that can happen (although it shouldn't ever happen in practise). Attached is a patch that adds a test and fixes the issue. |
