B102: Test for the use of exec
|
||
|
|
==============================
|
||
|
|
|
||
|
|
This plugin test checks for the use of Python's `exec` method or keyword. The
|
||
|
|
Python docs succinctly describe why the use of `exec` is risky.
|
||
|
|
|
||
|
|
:Example:
|
||
|
|
|
||
|
|
.. code-block:: none
|
||
|
|
|
||
|
|
>> Issue: Use of exec detected.
|
||
|
|
Severity: Medium Confidence: High
|
||
|
|
Location: ./examples/exec-py2.py:2
|
||
|
|
1 exec("do evil")
|
||
|
|
2 exec "do evil"
|
||
