Advisories for Npm/Immer package

immer is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')

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.

immer suffers from a prototype pollution vulnerability in the applyPatches_ function of patches.ts.
