How to update list item without having permission on list

Question

If the user does not have permission on list and want to update the list item, how to achieve that without using Elevated privileges?

Answer 1

You can not update a listitem without having permissions on it. Running with Elevated privileges is the solution for your problem. Apart from that i don't think there is a solution for it, because it would be a security issue in SharePoint.

Otherwise you can check other impersonation methods for this.
