PDF Viewer CSP issue

Hi team,

I experience a Content Security Policy issue with the pdf viewer widget.

Dojo: https://dojo.telerik.com/qPYnmOBn

It seems to be dependent of the file though but not quite sure. Try this pdf file : https://www.arcep.fr/uploads/tx_gspublication/referentiel_general_ecoconception_des_services_numeriques_version_2024.pdf

and go to page 20 for instance.

Please advise.

Regards,

Laurent.

Hi Neli,

Thank you for your prompt response.

I confirm that on my end the error occurs with different files. 

Furthermore, if you dive into browser dev tools and try to inspect the error you will find that kendo code is dealing with html fragment having inline styles.

Please look the file attached.

Regards,

Laurent

Hi Laurent,

The issue seems related to the styles applied in this specific PDF file. I tested with multiple files on my side, but the issue does not seem to appear. Thus, I assume that there are inline styles in the provided file that are causing the observed issue. Could you please confirm if on your end the error occur with different files?

What we can control is the PDFViewer component to not apply inline styles on the page. However, such scenarios where the issue is caused by specific files are out of our control as we cannot control the uploaded file content.

I remain at your disposal should you have any questions.

Regards,

Neli
