As soon as I read this

>Shared dev boxes, shell-as-a-service, jump hosts, build servers — anywhere multiple users share a kernel. any user becomes root

jumped out of bed and went straight into webminal.org servers as local user and ran the python code. It says permission denied on sock() call.

Then I tested with local laptop with it:

```

$ uname -a

Linux debian 6.12.43+deb12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.43-1~bpo12+1 (2025-09-06) x86_64 GNU/Linux

$ python3 copy_fail_exp.py

# cd /root && ls

bluetooth_fix_log.txt dead.letter overcommit_memorx~ overcommit_memory~ overcommit_memorz~ resize.txt snap

```

It does provide the root access!
