Non-Compliant Code Examples

import asyncio

def handler(event, context):
    # Should sanitize arguments
    async_loop.run_until_complete(async_loop.create_subprocess_shell("mycommand"))

Compliant Code Examples

import asyncio
import shlex

def handler(event, context):
    # Should sanitize arguments
    async_loop.run_until_complete(async_loop.create_subprocess_shell(shlex.quote("mycommand")))
