  - If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution,
    they could have achieved execution of attacker-controlled JavaScript code in a privileged context.
    (CVE-2022-1802)

  - An attacker could have sent a message to the parent process where the contents were used to double-index
    into a JavaScript object, leading to prototype pollution and ultimately attacker-controlled JavaScript
    executing in the privileged parent process. (CVE-2022-1529)
