What it is

🚨 An unauthenticated user can change any admin's password, like a bank teller who lets anyone walk in and update vault codes! 🔥 Imagine a secure building where the front desk has no security checks — anyone can claim to be an employee and access restricted areas. That's exactly what this vulnerability allows! This devastating flaw means a malicious actor could lock out your administrators, gain unauthorized access to critical systems, and wreak havoc with sensitive data. The potential for chaos is enormous, as attackers could impersonate administrators and manipulate systems at will!
