What it is

⚠️ A crafty HTML page can exploit this flaw. With incorrect reference counting in AppCache, a remote attacker could escape the sandbox in Google Chrome versions before 70.0.3538.67! Think of it like a poorly designed amusement park where the security gate allows visitors to slip through without a proper ticket — once they’re inside, they can access any ride and create chaos! This vulnerability could allow an attacker to break out of the secure environment that Chrome provides, potentially leading to unauthorized access to sensitive user data. Imagine a mischievous park-goer dismantling the ride safety measures and putting everyone at risk — it's a serious threat!

Put simply

Think of it like a poorly designed amusement park where the security gate allows visitors to slip through without a proper ticket — once they’re inside, they can access any ride and create chaos!

Essentially, this allows them to execute code outside the restrictions normally imposed by the browser.
