CVE-2021-23436 [HIGH] CVE-2021-23436 immer: type confusion vulnerability can lead to a bypass of CVE-2020-28477
CVE-2021-23436 immer: type confusion vulnerability can lead to a bypass of CVE-2020-28477
This affects the package immer before 9.0.6. 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']). The === operator (strict equality operator) returns false if the operands have different type.
