CORS error when logos are hosted elsewhere #21113
Description
Describe the bug
We have authentik configured in HA, so we use a different host for serving things like backgournds, logos, etc.
Now hen a user logs in to the user portal via auth.brand1.com, the logo images for the applications display normally, because they are hosted at static.brand1.com.
When a user now login via a different brand, auth.brand2.com the logos in the user portal are not displayed because of CORS errors, since they are hosted at static.brand1.com.
How can this be rectified?
How to reproduce
Host logos outside of authentik.
Set logo for application to URLS that is same domain as Brand 1
Login to Brand2
No logos are displayed becasue of CORS errors.
Expected behavior
I would expect the logos to be displayed correctly.
