Just test your minimal 3 line script with the example input I've given
you. It breaks:

# cat > sample.sh
#! /bin/bash

CMD=(touch "$@")
bash -c "${CMD[@]}"
# ./sample.sh "this is file one" "this is file two" "file
>
# bash -x ./sample.sh "this is file one" "this is file two" "file \" f"
+ CMD=(touch "$@")
+ bash -c touch 'this is file one' 'this is file two' 'file " f'
touch: missing file operand
Try `touch --help' for more information.

Bash (line runuser) expects a line of shell, quoted/escaped
appropriately, as a single string param -c

*that* is the challenge.
