BUG/PROBLEM REPORT / FEATURE REQUEST

Description:

In a restricted Python package environment, the following code snippet:

python 3.10.0

try:
 exec("import os; os.system('ls'); print('**')")
except:
 pass

successfully executes without throwing an error, despite exec being expected to be undefined in such a restricted environment.

However, when the code is run without the try-except block:

exec("import os; os.system('ls'); print('**')")
an error is thrown as expected.

Expected Behavior:

The restricted environment should prevent the execution of exec and throw an error when it is invoked, regardless of the surrounding try-except block.
