embedded javascript security risk question

rnehrboss — Sat, 04 Jun 2022 03:59:52 GMT

Hi,

I've gotte embedding with a capacity working.

I check to see what user is logged in and create a filter to pass through the javascirpt API.

Power BI works great shows charts with filtering etc.

I'm now concerned about the security implications.

If I load the page and then view page source, I see the javasciprt with the access and embed tokens, as well as my filters.

It seems like someone had access to the page, they could just take the page source, and change filters and create a new page that would give them access to other data (not allowed based on their own filters).

Am I missing something?

I don't want to use Row Level Security, because we manage users and persmissions in web app.

Thanks!

Hi @rnehrboss ,

The problem is that different users will get the same token. For the dataset, the kind of data it can give to the user is based on the token.

If you want different users to get different tokens with different permissions, then there are only two ways to do that according to the official documentation.

If you are handling data from multiple customers, consider these two approaches for securing your data: Workspace-based isolation and Row-level security-based isolation.

For more details, you can refer this link.
