⚡ Just by tweaking the $HOME environment variable, an attacker can run any command they please on a system using chrome-launcher! Think of it like a waiter who serves your meal based on a single note with your name on it — if someone swaps that note, they can change your order completely without you knowing. This vulnerability lets attackers misdirect commands to execute their bidding. An attacker with control over this variable can execute arbitrary commands on the host system, which could lead to unauthorized access to sensitive data, installation of malicious software, or even complete system takeover. It's a surprisingly sneaky way to exploit what should be a trusted environment.
