Salesforce’s Spring ‘20 Release: Changes regarding guest users starting March 1, 2020

Hi Nicholas, it depends on which variables you’re passing as params. The guest user will need to have access to those variables (e.g. record ids).

Remember
 that there is not distinction between guest users from a security standpoint, so any guest user familiar with the Javascript console can use it to access all the records that are open to guest user access regardless of how Skuid’s conditions are set up.
