Summary
Prototype Pollution in immer
Details
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.
