Code injection can occur in the OJS report generator if an authenticated Journal Manager user visits a crafted URL, because unserialize is used.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
