Prior to version 3.14.0, cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect. 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. Version 3.14.0 patches the issue. If unable to upgrade, using a `Cookie` header in the `headers` parameter is not vulnerable.</p> <p><strong>Affected:</strong> aio-libs aiohttp</p> <p>AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python.
