Issue with PowerPoint Add-in (data leaks through thumbnails)

[mobiandra]

Despite the anouncement on March 2024, my PowerPoint still shows my Power BI Visuals in the Slide Thumbnails without checking for permissions.

1. I use the Power BI Add in in PowerPoint and add a Report with Live data

2. I save the PowerPoint Slides

3. I send the PowerPoint Slides to anyone in the world (who should not have access to the Power BI Report).

4. The receiver sees the Power BI data in the slide thumbnails.

5. After opening the slides in edit mode, finally the permissions are checked and after a few seconds the Power BI visual disappears and the user sees "you can't view this content in PowerPoint". But the data is already leaked.

Anyone else experiencing this issue?

I use:

PowerPoint Add-in (https://app.powerbi.com/storytellingaddin) Version 2.0.0.3

Office Version 2405 (Build 17628.20188)

Just a short update to finish this off: This had nothing to do with Power BI.
It seems, I was in some kind of test group that had a pre-release version of Office 365 installed. Some days later, I was down-graded to the latest released office version and the bug was gone.

Hi @Anonymous ,

Thanks for taking time to have a look at this. Strange, that it works for you.

I just repeated a super-minimal PoC:

I open a blank report

I use "enter data" to add 5 rows

I create a bar chart

I publish to a Workspace on Power BI Service

I open the report in Power BI Service (by default it has no sensitivity label, as you can see from the screenshot below)

I click on "Export" > "Power Point"

I open the Power Point

For editing, my organization requires me to choose a sensitivity label. I choose 'Public'.

I save the PowerPoint and send it to my other Email Adress, which is outside of my Organization (before I can send the email, my company wants me to add a sensitivity label for the email. I choose "Public")

I open the Email and download the PowerPoint. I open the PowerPoint and see the Bar Chart:

I click on "Enable Editing" and the Bar Chart disappears:

So, no RLS, no refresh schedule, really nothing special.

I am wondering if it has anything to do with the sensitivity labels. So, I also tried classifying the report as internal before exporting to PowerPoint, but this didn't make a difference.

Would really appreaciate help with this. 

Best regards,

Alexandra

Hi @mobiandra ,

According to your description, I took a report from power bi service and shared it to PowerPoint.

Saved the PowerPoint and shared it with other coworkers who did not have any permissions. The result was as expected, they could not see any data either in the web page or in the PowerPoint.
I use:
PowerPoint Add-in ( https://app.powerbi.com/storytellingaddin) Version 2.0.0.3
Office Version 2408 (Build 17928.20114)

Can you provide more information so I can reproduce your problem, for example:
The type of data source and schema used.
Does the semantic model use RLS?
Does the semantic model use incremental refresh?
etc.

If your Current Period does not refer to this, please clarify in a follow-up reply.

Best Regards,
