GHSA-HG6J-4RV6-33PG 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...

Origin Validation Error

Overview Affected versions of this package are vulnerable to Origin Validation Error via the cookies parameter, which is processed by connectandsendrequest in client.py. An attacker who can control a redirect on a request that passes cookies on a per-request basis can expose data from those...
