What it is

⚡ A new installation could unwittingly open the doors for non-admin users! In Splunk Enterprise for Windows versions below 10.0.2, you might find your installation directory left wide open. 🔍 It's like a restaurant accidentally giving patrons the keys to the kitchen — anyone could wander in and access the whole menu, including ingredients that should be kept secret! This misconfiguration could allow unauthorized users to explore sensitive data, manipulate settings, or even execute harmful actions. It's a risky situation where all it takes is one curious non-admin user to cause serious trouble or leakage of confidential information.
