I'm seeing this critical update in my environment. According to this, I need to remove the update, delete, View All Data, or Modify All Data permissions enabled for guest users.
On one of my public pages, I'm doing an update on the Contact record. If I remove update permission from the guest user, My end user will not able to update their contact information.
What are the alternatives to this? How can I allow updates on Contacts without giving access to salesforce?
