We have users that submit data on their profiles. This is very sensitive and personal data.
We use tables and conditional filters to display only data that belongs to the currently logged-in user. It means that for each table or list block we have to use conditional filters to the currently logged-in user, but if we accidentally miss one, it can be a big issue.
Unfortunately, we missed one table and one user was able to see the data of another user. It wasn’t an issue because we caught it early and no one realized that this is sensitive data but I think limiting it on a global level is an important feature going forward to avoid such embarrassing scenario
