If an object prototype was corrupted by an attacker, they would have been able
to set undesired attributes on a JavaScript object, leading to privileged code
execution (CVE-2022-2200).

An attacker could have injected CSS into stylesheets accessible via internal
URIs, such as resource:, and in doing so bypass a page's Content Security
