      "value": "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."

      "value": "Esto afecta al paquete immer versiones anteriores a 9.0.6. Una vulnerabilidad de confusi\u00f3n de tipo puede conllevar a una omisi\u00f3n  de CVE-2020-28477 cuando las claves proporcionadas por el usuario usadas en el par\u00e1metro de la ruta son matrices. En particular, esta omisi\u00f3n es posible porque la condici\u00f3n (p === \"__proto__\" || p === \"constructor\") en applyPatches_ devuelve false si p es [\"__proto__\"] (o [\"constructor\"]). El operador === (operador de igualdad estricta) devuelve false si los operandos tienen distinto tipo"
