Kentico 13 CMS: VAPT scan issue for Deserialization Of Untrusted Data

Quan Lee asked on May 20, 2022 04:58

Hello guys, Our client using VAPT scan and has deteched a issue belongs to CMS OOTB code (path is: CMSModules/ImportExport/Controls/ImportWizard.ascx) Basically in the EnsureLicenseFromPackage method, they have a suggestion to use other Serializers instead of using BinaryFormatter to be safer. Can we have any patch to fix this or do I have to update it by myself? If change to another Serializer, will have any risk?

Thank you so much!
