QID 981061

QID 981061: Nodejs (npm) Security Update for immer (GHSA-33f9-j839-rf8h)

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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
