I ran the GUAR report and was able to complete some of the recommendations. However w.r.t custom object "Profile Read Access" and "Profile Create access" - it says potential risk (yellow) as the Guest User profile has "Read" and "Create" access on that object.

As the Guest user needs to create records on the custom object as per the functionality, I assume we can ignore this and keep the object settings as is. All i understood is the Guest User should not have Edit access on the object. Can someone please advise?
