Technical details
The create_redirect_client() method removes Host, Proxy-Authorization, and Authorization headers on cross-origin redirects but leaves Cookie and Cookie2 headers attached. An attacker controlling a redirect response or network position for non-HTTPS origins can intercept these cookies. The vulnerability affects versions prior to 0.51.0; a fix was applied to strip Cookie/Cookie2 headers alongside the other sensitive headers.
