Kerentanan Access of Resource Using Incompatible Type ('Type Confusion') pada immer project immer. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

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.
