Cross-Origin-Opener-Policy 0 of 5
Cuts the link between the product's window and windows opened by, or opening, other sites.
Without it: A page that opens the product keeps a handle on its window and can later redirect it to a look-alike sign-in or payment page (tab-nabbing) while the user thinks they are still on the real site. It is also part of the isolation browsers need to defend against Spectre-style attacks.
-
Cross-Origin-Resource-Policy 0 of 5
Tells browsers which sites may load this site's resources.
Without it: Other sites can pull the product's responses into their own pages, which makes side-channel leaks of what a signed-in user can see easier.
