Description alexandre robuchon 2021-03-22 08:19:42 PDT 
Macos: 10.15.7 
Safari: Version 14.0 (15610.1.28.1.9, 15610)

A pdf served with Content-Security-Policy header to "default-src 'none'; style-src 'self' 'unsafe-inline';" is not displayed in Safari. It complains about not having 'object-src' set to 'self'.

This header works fine in Chrome, Edge, Firefox ...


Is it something that will be fixed or is it the intended behavior ?


thanks.

This seems unlikely to be intended if it's different from other browsers. Probably an artifact of having PDF loading implemented using plugin code paths.

Kate, is this related to https://trac.webkit.org/changeset/271650/webkit?
Comment 3 Tim Horton 2021-03-22 13:35:54 PDT 
(or maybe a dupe of it?)
Comment 4 alexandre robuchon 2021-03-22 14:16:19 PDT 
It looks related indeed. Sorry I didn't find the ticket.


Is the patch in 14.0.3 or do I need to get the nightly to test this ?

You should be able to test it using the latest Safari Technology Preview (https://developer.apple.com/safari/technology-preview/).

It works like a charm. No plugin error.
