CVE-2021-23436
CRITICAL9.8EPSS 0.55%Prototype Pollution in immer
發布日:2021/9/2修改日:2025/1/14
描述
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.
受影響套件(1)
