⚡ Authenticated attackers can slip shell commands into your PDF downloads, turning a simple report into a potentially dangerous script! 🔥 Think of it like an unsuspecting diner at a restaurant who orders a meal, but the chef secretly adds extra ingredients that can cause havoc — in this case, harmful commands instead of spices. The PDF generation process is like that kitchen, accepting unchecked ingredients and potentially serving up trouble! An attacker able to export PDF reports could inject malicious shell commands, leading to unauthorized access or even full control over the server. Picture someone sneaking in and altering your order, causing chaos when you thought you were just getting a report!
Think of it like an unsuspecting diner at a restaurant who orders a meal, but the chef secretly adds extra ingredients that can cause havoc — in this case, harmful commands instead of spices.
