In this case hydration enthalpy comes into picture,since we are taking about aqueous solutions \(Cu^{2+}\) has higher hydration enthalpy than \(Cu^{+}\) because of its small size and higher charge.

See@Souryajit Roy This is an example of disproportion reaction .As mentioned by@Krishna Sharma HYDRATION ENTHALPY comes into effect.

In aqueous solution, \({ Cu }^{ + }\) disintegrates into \({ Cu }^{ 2+ }\) and Cu. Well , I hope you may have asked the question after coming across this phenomenon, isn't it @Souryajit Roy ?
