What it is

⚠️ A crafted website is all it takes to execute arbitrary code in vulnerable versions of Apple Safari! Think of it like a restaurant that serves food from a mysterious kitchen — you might end up with an unexpected dish that could make you very sick.

This can lead to a denial of service, leaving users unable to browse their favorite sites and potentially exposing sensitive data.
