What it is

🚨 An attacker can bypass critical authorization checks and force your certificate provisioning process to be as easy as pie! 🍰 Think of it like a restaurant where someone can order a gourmet meal without ever making a reservation. The kitchen doesn’t check if the person is allowed to eat there — they just get the food right away! This could allow malicious users to generate unauthorized certificates, leading to a complete compromise of trust in your systems. Imagine the chaos if someone could impersonate your server or application, intercepting sensitive data or executing man-in-the-middle attacks! Absolutely devastating!
