Sensitive information sent insecurely In python-aiohttp

Description

AIOHTTP is vulnerable to cross-origin redirect with per-request cookies

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.
