Steps to reproduce

Cross-origin read blocking, better known as CORB, is an algorithm by which dubious cross-origin resource fetches are identified and blocked before they reach a web page. CORB reduces the risk of leaking sensitive data by keeping it further from cross-origin web pages. In most browsers, it keeps such data out of untrusted script execution contexts. In browsers with Site Isolation, it can keep such data out of untrusted renderer processes entirely, helping even against side channel attacks.

    • FYI: I’m about to land the Fetch PR. It standardizes all the bits of CORB that can be implemented without sniffing the response. Tests can be found in fetch/corb in web-platform-tests.
