Put simply

Think of it like a waiter who forgets your order and instead serves you a surprise dish that causes chaos in the kitchen — unexpected and potentially disastrous! 🥴 The bug resides in the browser engine of affected versions, allowing attackers to craft unknown vectors that disrupt normal operations. This could inadvertently lead to a Denial of Service or even enable attackers to execute harmful code.
