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." }, { "lang": "es", "value": "Esto afecta al paquete object-path versiones anteriores a 0.11.6.
