Description
Summary
Cookies set with the cookies parameter on requests are sent after following a cross-origin redirect.
Impact
If a developer uses the cookies parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect.
Workaround
If unable to upgrade, using a Cookie header in the headers parameter is not vulnerable.
