A type confusion vulnerability can lead to a bypass of CVE-2020-28477 when the user-provided keys used in the path parameter are arrays. In particular, this bypass is possible because the condition (p === \"__proto__\" || p === \"constructor\") in applyPatches_ returns false if p is ['__proto__'] (or ['constructor']).
