What it is

🚨 An authorized attacker can elevate local privileges with a few clever moves!

Surprising, right? This vulnerability could lead to unauthorized access to sensitive data and system control, allowing attackers to perform any action as a higher-privileged user. Imagine losing control of your entire system because someone slipped past the front desk!
