"CVE-2021-23434"
],
"details": "This affects the package object-path before 0.11.6. A type confusion vulnerability can lead to a bypass of CVE-2020-15256 when the path components used in the path parameter are arrays. In particular, the condition `currentPath === '__proto__'` returns false if `currentPath` is `['__proto__']`. This is because the `===` operator returns always false when the type of the operands is different.",
