This is like a magician performing a trick that leaves the audience believing they’re still behind a safe barrier, only to find out they’ve actually stepped out of the magic circle and into a dangerous situation! The vulnerability stems from a use-after-free flaw in the Cast UI component of Google Chrome, where an object is accessed after it has been freed, allowing attackers to manipulate memory in a way that can lead to a sandbox escape.
If a crafty attacker tricks a user into interacting with a specially designed page, they could potentially break out of Chrome's sandbox.
