Photo upload doesn't work

When I try to upload a photo to my profile, it doesn't upload it.

How to reproduce: Access the user profile page and click on the photo to upload a new photo. Choose an image from your files and validate.

I get the following message in the console:

Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at blob:http://canaille.localhost:5000/025d8970-7ec9-4de5-b26a-9f414e1e6246 because it violates the following directive: “img-src 'self' data: https:”

Note: This bug occurs both on local development server and production server (auth.yaal.coop).
