Descriptions

The package metacalc before 0.0.2 are vulnerable to Arbitrary Code Execution when it exposes JavaScript's Math class to the v8 context. As the Math class is exposed to user-land, it can be used to get access to JavaScript's Function constructor.

El paquete metacalc versiones anteriores a 0.0.2, es vulnerable a una ejecución arbitraria de código cuando expone la clase Math de JavaScript al contexto v8. Como la clase Math está expuesta al contexto del usuario, puede ser usada para conseguir acceso al constructor de funciones de JavaScript
