Why do you think it's different?

Agreed.

Also gtfobins is a great resource in addition to shellcheck to try to make secure scripts.

For instance I felt upon a script like this recently:

#!/bin/bash
# ... some stuff ...
tar -caf archive.tar.bz2 "$@"

Quotes are OK, shellcheck is happy, but, according to gtfobins, you can abuse tar, so running the script like this: ./test.sh /dev/null --checkpoint=1 --checkpoint-action=exec=/bin/sh ends up spawning an interactive shell...

So you can add up binaries insanity on top of bash's mess.
