New Can I Trust Test Case: Browser returns secret out of pre-cached response in a CORS-Request

Nov 13, 2020

A new Can I Trust Test Case ist available.

This time the topic is the following:

What is

Browsers nowadays have a lot of built-in security features to help make the web more safe by default. Although this is a great thing, unfortunately, different browsers implement these features slightly different than other browsers. And sometimes, the implementations also differ from browser version to browser version.
