In this work, we report for the first time the detection of the high-energy cutoff ($E_{\\rm cut}$), a direct indicator of thermal coronal radiation, of X-ray emission in Mrk 348 ($z$ = 0.015), a young radio galaxy classified as compact symmetric object. With a 100 ks NuSTAR exposure, we find that the high-energy cutoff ($E_{\\rm cut}$ ) is firmly detected ($218^{+124}_{-62}$ keV).
